The Secret of Successful voip


VoIP technology was introduced to the mass audience in the year 2004.We at Welcome Telecom gives early adopters, with a good concept and under your budget, were willing to overlook obvious quality issues. Earlier people had to lead with call drops while using cell phones but by using VOIP these problems will be avoided. While VoIP marked a technological leap forward for network management and lower budget, audio quality took several steps back.

However, same way the network and technical advances have widely overcome cell phone problems and high definition has provided a new standard for television, VoIP quality for home and business phones is much better than the earlier days.


IP can take the voice communication to the next level. While there are many ways to save cost and many features that come with VoIP systems, the main advantage is the voice quality. VoIP call quality has not only matched Public-Switched Telephone Network (PSTN) quality but it gives companies to far surpass PSTN with wideband audio. Voice is the most crucial component of any communication system because it creates a personal bonding between people. The ability of VOIP is crisp and clear voice which is very important in todays world and also while contacting with international clients.


A VoIP system is also referred to as IP PBX. Although the specifications of each system are different from one another, there are some basic elements in each VoIP network:

• Endpoint. It is used to send and receive calls.

• Proxy Server. VoIP connections are controlled through endpoint registration, authentication, and call setup and tear down.

• Message protocols. The message protocol used to communicate with the proxy server. It is used for registration, call setup and tear down, and also helps determine which CODEC is used for the call. SIP, H.323, SCCP, and MGCP are all message protocols..

• CODEC. A system used to encode and decode the audio into RTP packets. The CODEC always have a big impact on audio quality because it specifies the audio bandwidth.

• Session border controller (SBC).

• Media gateway. It provides translation between VoIP phones and the phones which are not on the network such as external landlines, PTSN, and cell phones.

• IP Network. Carries network and VoIP data. Both the corporate intranet and the public Internet is included. Extra things may come into play, such as a DHCP server to assign an IP address and a DNS server to assign and manage domain names.


VoIP will soon become the standard in corporate communication, with 80% companies will take up this services by next year. Because VoIP supports wideband audio that is more than double than the PSTN, users can hear more natural sound and increased intelligibility. The benefits of VoIP naturally extend into the conference room. Users always expect high-level sound quality without clipping or frustrating ambient noise something that regular VoIP speakerphones can’t provide.
