Understanding VoIP Protocols

Nearly any device ever designed to transmit video and audio packets between computers that communicate with one another, uses Real-Time Protocol (RTP). After the can serve as became evident that people communicating online has the potential for ease dropping on their communication, RTP (Real-Time Protocol) was enhanced to us more secure level. The secure RTP was developed for authentication, encryption and integrity of the video and audio packets that were transmitted online to communicating devices.

Part of the process of transmitting video and audio media between computers is the employment of various protocols. One such protocol locates the remote device to negotiate exactly how the media will transfer flow between each device. These types of protocols are known as call-signaling protocols, with the most popular being SIP (Session Initiation Protocol) and H.323. Each protocol relies on static provisioning and other protocols as a way to locate a variety of users.

First originated 1995, both SIP and H.323 were developed to solve the initial communication between two computers as a way to effectively exchange video and audio media streams. H323 experienced commercial success while SIP progressed at a slower level before being recognized as a standard in 1999.

Both protocols have the ability to perform the same action: to establish a multimedia level of communication including video, audio and other communications. However, there are designed significantly different with SIP being ASCII-based and H.323 being built on the foundation of binary protocol and legacy communication systems.

Although the jury is still out on whether SIP or H.323 can be held as the true standard for media transfer functionality, no one disputes the fact that both perform well. However, H.323 appears to be superior in a variety of ways including offering better support for videos, optimal interoperability with PSTN, premium interoperability of legacy video systems a more dependable out of band transport of DTMF.

Alternatively, SIP (Session Initiation Protocol) was never designed to work as a solution for the problems handled by H.323. Additionally, it gained its popularity by misinformation of being “easy to debug and implement”. Built as a complex communication system, they both perform identical amounts of work using to different approaches.

Of the two, SIP implementation is far easier to troubleshoot or develop. Likewise, H.323 is still the protocol to use in bulk VoIP deployments, especially when transmitting voice calls globally. Additionally, H.323 is the protocol most used for room-based videoconferencing and serves as the #1 protocol for nearly all IP-based video systems.

Hosted PBX Adoption Expected to Rapidly Increase

Modern-day advances in digital communications have strengthened the position that Hosted PBX providers, like BroadConnect Telecom, hold over traditional telecommunications providers. Such advances have enabled end users everywhere to reap the advantages of a full service digital platform, while enabling them a unified communications platform to keep costs low.

This report concludes that enhanced Voice over IP (VoIP) services have far surpassed the capabilities of historic telephony services. Thanks to future-proof communications, this can now be considered a viable means of incorporating a full-service unified communications solution designed specifically to meet the unique challenges of the SME market. Recent studies would suggest that SME demand for quantifiable unified communications hosted services coupled with the industry preference for high quality VoIP service would present a competitive risk to the already unstable conventional telephony model.
Avaya Hosted PBX

Findings indicate that while small businesses have not been entirely smitten by the idea of leaving their old phone carrier behind, the Hosted PBX market is expected to rapidly increase over the next 3 years. In fact, it is estimated that the hosted services market will reach record highs at $1.2 billion by 2015; up from one-half billion dollars in today’s market. This substantial increase will come as a direct result of an accelerate adoption rate as more and more small business owners realize the immense benefits of Hosted PBX services.

From a businessman’s perspective, Hosted PBX delivers results that the conventional telephony carrier simply cannot. For example, smaller businesses can now take comfort in knowing that they have access to a high level of business-enhancing features, performance and service without the hassles and costly expense of doing business with the telephone company.

Furthermore, Hosted PBX services, from a reputable service provider like BroadConnect, delivers substantially lower operating costs and provides an efficient alternative to enterprise-owned, proprietary, and infrastructure-based phone systems.
