SIP Trunking Paves the Way to Affordable Communications in Enterprises

SIP trunking has emerged as the best alternative to traditional PBX (News - Alert) phone systems in enterprises. It allows businesses to replace traditional fixed PSTN lines with PSTN connectivity via a SIP trunking service provider on the Internet.

The growth of Voice over Internet Protocol (VoIP) services has helped increase the adoption of SIP trunking services. VoIP is now considered one of the cheapest communications technology; thanks to the development in this segment, businesses of all sizes and types are able to bring significant reduction in communications costs.

The best thing about SIP trunking is that it allows businesses to add SIP phones systems to their current PBX phone system services. Businesses can communicate with anyone within the company as well as outside their premises.

The advanced services offered by IP PBX help businesses deliver instant messages, emergency calls, conferences and much more by extending the technology beyond firewalls.

SIP trunks also bring significant cost-savings for enterprises because they eliminate the need for local PSTN gateways and the wires.

SIP trunking not only frees businesses from PSTN line investments, it also delivers affordable long distance calls, almost at the price of local calls. The service utilizes the bandwidth efficiently. As several servers are utilized in delivering the service, redundancy is ensured.

There are two types of SIP trunking services. The first type uses dedicated line, also known as leased line, which carries the highest call carrying capacity at a given time. This is the most reliable service, but is more expensive than other options. It does not require a Virtual Private Network.

Businesses can also opt for shared lines. These are also dedicated lines but they are shared with other IP traffic. These lines too do not require VPN. The disadvantage with this system is that it cannot handle huge traffic.

Considering the several advantages of SIP trunking, small and medium-sized businesses are implementing the service to help lower costs compared to analog circuits and PRIs, yet offering the same quality of service, says a blog post from White Label Communications.

SIP phone providers are betting big on this market opportunity. Companies like Panasonic (News - Alert) are offering highly advanced SIP phones that allow businesses to enjoy unified communications, collaboration, presence and more.
