Reason to switch to using the model of phone Internet protocol (Voice over Internet Protocol - VoIP) can be mentioned a lot, depending on whether you want to develop business models and operations of the business ( DN) how you. However, according to documents from Customer's Avaya corporations, is 10 the most important reason to use the phone system (phone) IP (IP Telephony) or VoIP service.
Transition strategic direction of service providers and VoIP
According to many experts, the coming few years will be about 300 billion U.S. dollars of investment funding for telecom industry was transferred to the equipment and network services to support IP Telephony solutions over LAN and the VoIP service package on the WAN. Thanks to appear at the right time, network technology to support IP Telephony and VoIP has influence and impact a strong market to provide telecommunications services.
Diverse functions - high economic efficiency
Most of the features of the phone system Phone POTS-PSTN (Plain Old Telephone Service - Public Switched Telephone Network) has made a tradition of "name" in the field of telecommunications and became very familiar to us. The outstanding features as possible to the voice mail (voicemail), transfer calls between your branches (call tranfer), call forwarding to some other phone (call forwarding) and the call triangle (three - way calling). Cost [the investment or use] of these features can be included in the cost of [the investment or use] of the enterprise phone system, or user fee for using these features as form of separate services are integrated on individual subscriber Tel.
Obviously IP Telephony and VoIP have made phone features traditionally become obsolete as all features, applications communicate new information has presented the world converged telecommunications platform support IP. Number and type of phone features available in the IP Telephony and VoIP solutions today are rated as very much and attractive. All this functionality is available without requiring any additional investment costs because they do work on IP network platforms and be "shipping" on your computer medical computer applications as usual.
These features are effective in IP Telephony and VoIP solutions - such as the ability to check the station phone you are using (or exactly are connected to) and get a "virtual sign" through which inform you that someone in the group calls its "presence" but is busy answer / make a call or away - have proved so superior to any system that features POST Phone System provides.
POTS phone system, separate systems must always be maintained to manage existing user on the system and information about them. Depending on the POTS phone system that businesses are using, the manager must set the user's information and update data on selected list of phone systems.
Meanwhile, the telecommunications system converged IP platform, most (if not to say all) information as may be updates only once and stored (maintained) in an institution homogeneous data. Whether companies are using ERP (Enterprise Resource Planning) or DBMS (Database Management Systems), the software is integrated with all related application systems in enterprises when necessary, including all systems IP Telephony and VoIP today through communication Application Programming Interface (API).
Investment cost savings VoIP ago
Today, most organizations and companies are using (or also more) model of the traditional phone system, or converted in whole or in part to IP Telephony and VoIP systems to support better for business. If the company has equipped digital devices (eg PBX), you can save considerable investment costs by reusing most of the equipment with new VoIP system.
Easy maintenance
Thanks to the ability to remove root systems get more information duplication and redundancy, the task of installing and managing VoIP and IP Telephony systems becomes easier. The management system phone offered many applications efficiently and directly to support the many challenges they encounter. They not only manage the application data on computer systems but also phone or video conferencing (video conference) on the IP platform.
The action moves, additions and changes (user information or system configuration) in the POTS phone system requires resources previously complex and very expensive, but with an IP Telephony network is VoIP automatically self-adjust to be compatible with the new location of the user. System managers can be from any networked computer that conducted the inspection setting purposes (usage), account (account) and other data users. With the IP telecommunications systems, public management and maintenance of the network phone becomes economically and efficiently.
Flexibility and mobility
IP Softphone is a software solution called Internet Phone for computers using Windows operating system. This software allows users easy access to telecommunication services in real time (with or without charge), and features improvements to the method used is simple: just click to dial call. In a telecommunication network IP platform, employees can travel freely anywhere in the office, connect the laptop to the network, start working and receive / make calls. Whether sitting in a position "temporarily" but people still provides full features available in computers at the main desk. Network will automatically identify the user and impose personal information (profile) of the user that the database's control system. Even employees can transfer calls to any phone on any desk in a temporary location (this phone is not necessary to support IP). With this model, the system administrator no costly and time to create compatibility between computer data and phone connections for a colleague is working temporarily at the office by their charge.
Many attractive features
If you are a manager (network computing or telecommunications in business) and still skeptical about the advantages of VoIP, such as reduced communication costs; easy integration of data systems, voice and video; database capable of centralized control; mobile features improved help save time and costs ... probably not something you can convince to switch to using the solution hey.
But just in case you face a barrier and not sure which way should you consider the phenomenon of alcohol emerged as "the SIP (Session Initiation Protocol) - allows multiple applications , new hardware easily deploy VoIP solutions on the LAN, WAN or Internet. Most of the current ADSL modem and router support VoIP and SIP, small and medium enterprises can quickly deploy Internet phone models through Internet connection with other free VoIP services such as IPTel, DrayTel, MediaRing, IPTEL, Voice777 ...
Ability to manage comprehensive
The telecommunication network provides the IP is always a platform for effective comprehensive management system. Therefore, you can control information to each bit of data flow on the network is IP Telephony (LAN) or VoIP network (WAN).
Similarly, you can use specialized tools, such as diagnostic tool system of Avaya EXPERT Systems Diagnostics, to quickly detect and correct these problems occur on the network. These tools also support monitoring site or remotely. In this dedicated network (the IP telecom network), voice quality can reach 99.99%. This number does not mean "problems never happen" but the environment the IP network convergence, the ability to detect early symptoms and change the settings before you have any problems do occur that has been improved significantly.
Collaboration time
If you are still skeptical about the benefits that IP Telephony and VoIP delivers, please consider the following fact: VoIP platform operating on IP networks and web applications previously only works on the Internet is now can operate on the IP network. Users can access the website you need right from the desktop phone or the IP link to the homepage of the particular phone being used. Currently, there are many Web-based applications-HTML suitable for operation on the IP phone.
Users can add images Solutions Phone Video Telephony Solution with software-based IP video applications, thereby allowing a desktop or notebook computer to simulate a IP phone in the office. Quality images and sound using the internal network usually better to use the internet connection is rarely encountered condition late hours or frame.
Bandwidth use reasonable
Many users completely wrong that the additional IP Telephony and VoIP solutions to the enterprise network computer network is not providing enough bandwidth to support this change. However, the fact that data flow computer (not a data device) on the regular phone network, accounts for 30% of the overall system bandwidth.
If the review terms of LAN, the ability to isolate failures is provided through switches, to help maintain a stable regime for the operation of the network. If any "dead spots" (chokepoint) are discovered, they can be overcome almost immediately by changing the point of connection or the network managers called "load balancing "(load balancing). However, the IP management system will tell you this before it becomes a problem.
If the review terms of WAN, the ability to download data (bandwidth) should be more focused. WAN bandwidth is often evaluated based on how many standard Service Channel Number (Digital Service Channels - DSOs) are supported.
For example, the transmission line T-1 (1.544Mbit / s) support 24 DSOs is one of the most common connection in the world today. If the phone system deployed in the form of POTS-PSTN switch via T-1 link, you can make 24 calls simultaneously. However, the advantages of VoIP is closing the data packets and data packets are transmitted via T-1 connection on a small portion of the bandwidth of a channel DSO. Therefore, you have the bandwidth of multiple VoIP services if compared with POTS-PSTN phone system on the WAN.
Reduce long-distance phone charges
If a company has many offices away from each other (in the cities, provinces or other countries), the VoIP will save considerable cost long distance phone calls between this office. All that companies need to do is adding hardware solutions and software appropriate to network your computers available. For a complete VoIP system, even businesses can deploy solutions intelligent call forwarding, which allows "limited" long-distance calls directly from a region (province, city or country ) to a different area (the area must have two offices of this company) by transferring data through the phone internal VoIP network and then forwarded to the PSTN system.
