Offering Free VoIP Calls to Haiti

T-Mobile isn’t the only contributor in the Haiti situation. Google, Vonage, Skype are offering Free VoIP Calls to Haiti. Ricky sent us in an interesting post on the Google Voice Blog this morning. It looks like Google is doing its part as well providing free calls to Haiti for the next two weeks using Google Voice.
“It’s impossible to watch the aftermath of the Haiti earthquake without wondering how one can contribute in helping the thousands of families who lost everything in this disaster.
Google set up a disaster relief page, which includes information and resources for anyone interested in helping out, and the Google Voice team also wanted to respond in our own way.
Particularly in the wake of such a catastrophe, for people in the US who have family in Haiti, it is critical to stay in constant contact with your loved ones, provide moral comfort, and offer daily updates to friends and family in Haiti.

Verizon Business Expands Unified Communications and Collaboration Consulting Services

Verizon Business is expanding its suite of UC&C Consulting Services to help enterprise customers more effectively integrate unified communications and collaboration with their business processes.

As part of this initiative, expert consultants from Verizon Business will collaborate with customers to define their objectives; assess their current infrastructure; look at where in an organization investment in these communications tools can make the biggest impact; create user profiles to pinpoint areas in which business processes can be improved; and help organizations overcome other hurdles to deployment and acceptance of these new communications tools.

CA Inc. is one of the customers that has used the Verizon Business professional consulting services, which it used both for its enterprise and contact center operations.

For more on the latest developments in unified communications and collaboration, TMC invites you to attend this week’s ITEXPO event in Miami, which includes a UC track. For specific information on what’s available, visit the track on her website

Avaya's Plan: Migrate Nortel Customers to Aura SIP-Based UC Platform

Putting to rest any fears about what the acquisition of Nortel’s assets will mean for hundreds and thousands of users, Avaya today unveiled a roadmap that details how it will integrate the products and services from the recently acquired Nortel Enterprise Solutions unit to create a new standard for business communications.
Avaya will speak in greater during this week’s ITEXPO show in Miami, held Jan. 20-22, about its new roadmap, and what it means to customers, resellers, carriers or developers.

“We’re talking about two worlds coming together,” Lawrence Byrd, director of UC architecture for Basking Ridge, N.J.-based Avayatold TMCnet. “The roadmap is not about ‘A’ versus ‘B.’ It’s about ‘C.’ ”

For the past year, that “C” has symbolized the emergence of an open-standards, enterprise-SIP architecture. In March 2009, Avaya unveiled the first fruit of its labors –Avaya Aura – aimed at next-generation communications for enterprises.


In further building a “better Avaya Aura” -- a SIP-based communication platform that unifies complex communications networks -- Byrd told TMCnet it will not use a “rip and replace” strategy. Instead, it will fuse the best technologies from Nortel with its own presence/messaging technologies.

Unified Communications Comes of Channel Age

One of the historic problems with unified communications is how disjointed this set of technologies has really been. Most customers are really still unsure what it means to unify their communications and the various components of unified communications solution don’t always work so seamless together.

But at the same time, interest in increasing the productivity of the existing workforce through the better use of IT is on the rise. The question is how can solution providers best leverage unified communications to meet the needs of customers while simultaneously advancing their own business goals? The answer to that question is to start thinking more like a carrier that is delivering set of services that have been customized for a specific customer.

How is Unified communications

Securing SIP Trunks

Security plays an important role for your networks and secure SIP trunk is one of these important jobs. SIP trunking provides organizations with a cost-effective, reliable method of connecting the internal network and telephony systems with external VoIP and traditional phone systems over the IP network. SIP tunking is quickly replacing traditional PRI and analog circuits for enterprise communications. Typically, SIP trunking involves an IP PBX, however Microsoft Office Communications Server 2007 R2 introduced the ability to do direct SIP trunking to the OCS 2007 environment and eliminate the IP PBX. Microsoft only provides direct SIP trunking with two VoIP providers, but Evangelyze Communications developed SmartSIP which lets organizations leverage their existing telephony hardware and employ direct SIP trunking with virtually any VoIP provider.

SIP trunking has many business benefits, but also introduces some additional security concerns. Internal security policies and controls will most likely differ from the security policies and controls of the SIP trunk provider. Connecting with the SIP trunk provider may involve opening ports though the firewall or NAT device, modifying the IP PBX (if present), changing private IP addressing or numbering plans, or other changes to the unified communications infrastructure. The organization must also maintain control over signaling and media secuity as well as call-routing policies.

SIP vs XMPP or SIP and XMPP?

History
SIP was invented to provide rendezvous for session establishment and negotiation on the Internet. XMPP (or Jabber) was invented to do structured data exchange such as synchronous or active presence and text communication among group of people. XMPP evolved from instant messaging and presence, whereas SIP evolved from Internet voice/video communication. Later, XMPP added support for session negotiation using the Jingle extension, and SIP community added extensions such as SIMPLE to support instant messaging and presence.

Technically comparing SIP and XMPP is like comparing apples and oranges because the core protocols serve different purposes: session randevous/establishment vs structured data exchange. On the other hand, because of the extensions invented in both the protocol worlds, SIMPLE and Jingle, they now have overlapping functions, and can be compared. When one compares SIP vs XMPP, actually the comparison is SIP/SIMPLE vs XMPP for IM and presence and/or SIP/SDP vs XMPP/Jingle for session negotiation. Even though the goals of the two sets of protocols are converging, there are fundamental architectural differences that I will enumerate in this article. There are other articles on SIP vs XMPP [1, 2, 3].

SIP in the view point of Google, Microsoft, Yahoo

In our last post, we discussed how GTalk2VoIP brings SIP capability to your instant messengers. Continuing our discussion with Ruslan Zalata, co-founder or GTalk2VoIP, today we will talk about SIP strategies of Google, Yahoo, and Microsoft. The interview extract follows (AS – Alok Saboo; RZ – Ruslan Zalata):

AS. GTalk2VoIP is essentially filling a gap by bringing SIP services to the ubiquitous instant messengers. Why do you think, Google, Microsoft, or Yahoo are not providing such a service themselves?
RZ: It’s about four years have passed by since we started our service. During all this time we cannot help hearing that Google, MS or other Biggie “just almost ready to deploy” a SIP/VoIP service, which will definitely kill ours and make whole consumer VoIP business seamless. Perhaps one day one of the biggies will finally come up with such a killer service, yet there are some obstacles I believe different to each company, preventing them from starting a killer VoIP service. Here are my personal thoughts:

Top Communications Trends in 2010

As a result of economic conditions in 2009, many companies also sought speedy deployment of converged communications in search of faster ROI. As we move into 2010 and beyond, Avaya’s top 10 communications trends are:

1. Proactive customer communications will enjoy a resurgence in popularity.

The falling cost and increasing sophistication of contact centre communications technologies such as voice and speech recognition systems, live and virtual agents, SMS, e-mail, presence, call routing, etc will allow businesses to deploy strongly beneficial outbound contact centre applications.

2. As the lines between devices and media continue to erode, analysis of employee communications will give companies greater flexibility at all levels.

Businesses will follow privacy standards, but also will increasingly track the phone calls, instant messages and e-mails of their employees to better predict work needs and behaviors. To meet that need, the communications industry will provide greater consistency across multimodal interfaces, whether through iPhones, standard telephones or the Web.

SIP in Unified Communications

Do you fire up your Gmail client to send an email to another Gmail user? And would that email fail to arrive if you used Outlook instead? Of course not and it's all down to the standard email protocol called SMTP. Every email client supports it so you don't have to worry what the other person is using. Likewise, HTTP delivers web content regardless of the browser being used.

This has always been the promise of SIP (the Session Initiation Protocol). Designed to establish, manage and 'tear down' communication channels between any media device, anywhere. Sound good?

SIP in Unified Communications

I'm not going to give you a definition of Unified Communications (UC) here, just hit Google and wade through all the interpretations that pop up. I do however, want to talk about how SIP 'underpins' UC.

It does this by ensuring that all elements of a business UC solution can establish connections to work together. It also allows for 'mid session' information to be passed between these elements to enhance the communications experience. A good example of this is starting up a whiteboard application with a colleague to give your existing conversation another dimension.

SIP/SIMPLE

Now UC isn't just about Instant Messaging, but I need to start somewhere.

The IETF SIMPLE (SIP for Instant Messaging and Presence Leveraging Extensions) working group focuses on the application of SIP to Instant messaging (IM) and Presence services. Invariably their work will affect any UC solution.

How Gtalk2VoIP brings SIP capability to your instant messengers?

We talked about GTalk2VoIP earlier as wonderful solution to SIP-enable your plain vanilla instant messaging client. GTalk2VoIP is an interesting service, bringing SIP service to your instant messenger. If you have not tried GTalk2VoIP, I would strongly urge you to try the service. While the service is great, we were not sure how the folks at GTalk2VoIP manage this feat. However, I was recently able to speak with Mr. Ruslan Zalata, co-founder of GTalk2VoIP, and he was kind enough to share some insights into the service and other technical details about how GTalk2VoIP brings SIP capability to your instant messengers. The interview extract follows (AS – Alok Saboo; RZ – Ruslan Zalata):

GTalk2VoIP_logoAS: For the benefit of our readers, can you introduce yourself?
RZ: My name is Ruslan Zalata, I’m a co-founder of GTalk2VoIP, Inc., one of the developers of GTalk2VoIP service and a piece of mobile VoIP (mVoIP) software called Talkonaut.

SIP Services Offer Cost Saving Options: Communications Provider

As more companies understand the benefits that Session Initiation Protocol, or SIP, services provide, adoption of the technology is on the rise. A recent report from Infonetics Research found that SIP trunking will likely become the second most commonly deployed service this year.
While widespread adoption of SIP services is still a ways off, businesses are looking more at the communication solution simply to save costs, according to a Cincinnati, Ohio-based communications provider. As signs of an economic recovery increase, companies still have cost savings solutions at the top of their list to keep their operations functional.

How An IP Phone Controls

Something that everyone ought to bear in mind of is how an IP phone works, specifically because of the multitude of benefits that you are offered by an IP phone and phone service. An IP phone works by using VoIP technologies that permits telephone calls to be made over the Net instead of through the ordinary PSTN system.

The IP phones use protocols like Session Initiation Protocol and Skinny Shopper Control Protocol, and can be merely software-based Softphones or purpose-engineered hardware devices that seem abundant additional like an normal telephone.

There are varied options when it comes to buying an IP phone for yourself, the most fashionable version being the wireless IP phone as a result of then you do not have any wiring or cable to fret regarding and it will be much easier and additional convenient for you to use. There are different sizes, designs and brands that you’ll select from, therefore opt for from a large choice and find one that’s simply right for you.

Bringing VoIP to Social Networking with IVR Technologies' Talking SIP

Social networking Web sites have become very popular in the past few years. For the most part, these sites are geared toward consumers rather than business users. And, while most let people stay in touch using text-based communications, voice capabilities to date has not been a major focus in the social networking market. But, this is changing.

In relatively recent research, The Yankee Group (News - Alert) predicted that subscribers to pure-play VoIP services will reach 6.4 million by the end of 2011 (up from about 2.8 million at year-end 2006). Meanwhile, Nielsen/Netratings estimated that use of social networking sites is experiencing almost 50 percent growth annually. Tie these two together, and it seems obvious that voice integrated with social networking is a huge market opportunity.

A Look Ahead at 2010

Wireless Internet - with the increasing use of handheld smart phones, wireless Internet usage will soar and with it will come increased congestion, reliability issues and eventually usage fees. The "all you can use" wireless Internet is going to get expensive.

Apple will end exclusive arrangement with AT&T - with competition from Google Android (the operating software for the "Droid") and ever increasing network congestion and performance issues on the AT&T network (see above), Apple will be forced to finally end their exclusive relationship and expand to other carriers. At first to other GSM carriers (T-Mobile) and then CDMA carriers (like Verizon and Sprint). However, an iPhone for CDMA networks requires a different radio in the iPhone which means there will end up being two different phones and users will never be able to jump from GSM to CDMA carriers without buying a new phone.

Almost 1.2 Billion SIP Users by 2012

Session Initiation Protocol (SIP) services will become the norm after 2010 and will rapidly begin to dominate the world’s telecom markets. By 2012 almost half of all telecom users will be using at least one SIP-based service, but more than likely will have many services from multiple devices able to communicate with other users and services across the Web and between enterprise and public networks. This will generate over $150 billion in service revenue annually with cumulative infrastructure capital expenditure of over $10 billion by that date.

A move to all-IP networks is the chosen path for introducing new services, with NGN the ultimate goal.

“The path to this all-IP goal is complicated: migrating existing services onto IP networks while retaining resources until they can be taken out of service is not a straightforward process,” says ABI Research analyst Ian Cox. “Mobile operators’ voice services are already optimized to reduce network traffic, and the move to VoIP is not an easy choice until the introduction of LTE or HSPA. One method that has gained some momentum is to use an IP overlay based on SIP. This allows new services to be designed and launched using a well-supported standard that also opens the way to bring Web services, service delivery platforms, and ultimately IMS into the network.”

Cox further comments that, “Using SIP, telephony becomes another Web application, which can be integrated into other Internet services. It allows service providers to build converged voice and multimedia services.”

By 2012, ABI Research expects almost 1.2 billion VoIP users to be active, most users also subscribing to several forms of messaging and video sharing driven by the interest in user-generated content. Additional services supported by SIP will include presence, click-to-dial, buddy lists, email and Web access which are assumed to be “core” services and will be included as standard in any service offering, and bundled with broadband access. A portion of the VoIP users will also be connected to a fixed-mobile convergence service.

”The Worldwide SIP Services Market” reviews the world market for SIP services. It includes forecasts for the market potential to 2012, including users (consumer and business), services revenue and capital expenditure. It forms part of three subscription Research Services: Mobile Operators, and Fixed-Mobile Convergence, and Wireless Infrastructure.

Founded in 1990 and headquartered in New York, ABI Research maintains global operations supporting annual research programs, intelligence services and market reports in broadband and multimedia, RFID & contactless, M2M, wireless connectivity, mobile wireless, transportation, and emerging technologies.

interview David Bryan on P2P technologies

Telecosm Interview: David Bryan on Peer to Peer Technology

I am pleased that David Bryan agreed to be interviewed for the first of what I hope will be a regular feature on the Telecosm blog: interviews! I am very interested in peer to peer technology and its many applications, and was thrilled when David agreed to help me launch this part of the blog. David Bryan wears two very big hats:



* He is Chief Executive Officer of Sipeerior Technologies, a leading provider of standards-based, OEM software solutions designed to enable serverless implementations of real-time communications applications.
* He is co-chair of the Peer-to-Peer Session Initiation Protocol (P2PSIP) working group at the Internet Engineering Task Force (IETF), the standards-making group for the Internet.

I am particularly pleased the David was able to take some time for the interview from his busy schedule, as there is an IETF meeting underway in Philadelphia this week.

What is the future trend of communications ?

Answer:
IP communications - Everything over IP (EoIP) :D
---
Everything over IP, is a collective term for the immerging culture of communicating and transporting data, of all sorts, over IP. VoIP Voice over IP is one of the first to lexically join the club. Although Post over IP (POIP), Company information, marketing and even trade over IP (HTML), News over IP, Games over IP are all embedded in the world of IP for many years.

The distance we have already come into EoIP is evident by the way we treat email and surfing as a part of life. Other medias, have yet to be marketed under the EoIP banner and like the previous technology may not be specifically associated with EoIP; TV and Radio over IP are available if under other names, Video over IP has been used for many years if under other guises used for person to person calls, conferences, eLearning, and many other uses. Books, Films and Music downloading is becoming the norm and IP internet connections are as important, to many people, as other services, electricity, gas, water, both domestically and in business. eBanking, eCommerce, stock prices and trading are all available over IP. International and inter-bank money transfers, ATM machines, credit card processing; online or in shops connect to each other over IP.

Many countries around the world are engaging in eGovernment and other types of digital citizenship. Signing documents legally with some form of digital signature will one day be the norm for everything from buying a house, getting married to voting, accessing education, taking exams and international travel. Medicine is not left out of this, there are many devices that can assist today with diagnosis, monitoring, drug administration and even surgery and this is just the tip of the iceberg.

British Telecom is spending £10,000,000,000 on a project called 21st Century Network (21CN), transforming the whole UK phone system to VoIP over the next 3 years. Leaving everyone with just a high speed DSL IP connection or an analogue voice only line (POTS), converted to VoIP at the exchange. The 21CN project will provide the UK with a pure IP communications network, another step and a mental shift in to the EoIP world.

Other countries such as Japan, Singapore and South Korea have thriving digital communities that are making the most of EoIP.

The term Everything over IP is a good way to name the direction we are going in (2007), but it is not a technology is it a buzzword or aspiration, filling in vocabulary as needed. This acronym has it is use now but will fade from the lime light when EoIP is as much the norm as email.

EoIP is of course not totally accurate until science makes some quite large jumps. It will be a long time before we have Me over IP and probably by then, if ever, IP will only be demonstrated in history museums, which you will of course visit over whatever the new communication protocol of the day is.
