Toll Traffic on SIP Trunks Increase

Research study findings from Eastern Management predict that toll traffic on SIP trunks will hit 42 percent by 2018. Involving more than 17,000 IT managers in seven world regions and 22 vertical markets, the study “SIP Market Size Analysis and Forecast 2013 – 2018” shows that more than 80 percent of companies with 20,000 employees say SIP is very important to their business. This is also true of companies with 100 to 500 employees.

SIP is simply a means of using Voice over IP (VoIP) over multiple trunks with the SIP protocol. It is an application-layer protocol that creates, modifies, and terminates sessions with multiple participants. SIP trunking helps companies gain great efficiencies from the trunks they get from carriers. It reduces calling cost to a great extent and you can turn all calls to local calls. Since calls travel over the Internet, or through the VoIP phone system to a termination point, the charges on long distance calls are reduced. SIP trunking also reduces the costs on separate voice and data connections and increases the benefits for communication systems using both voice and data together.

Perhaps knowing this, the companies responding to Eastern Management’s survey have led to the projection that by 2018, the number of companies using SIP 100 percent of the time for toll bypass will surge to 42 percent. Because SIP trunking is an IP-based telephony service, businesses get number flexibility which provides a whole host of other added benefits that can solve real business issues. SIP trunking also provides business continuity and is resilient.

What’s more, IP connectivity costs less than ISDN with lower call costs, free internal calls between extensions and offices, including international calls, and lower line rental costs for multi-sites. With SIP Trunking, businesses purchase only the trunks needed based on the maximum number of concurrent calls the business requires. SIP Trunks are significantly less expensive than analog lines, further helping businesses reduce costs. It’s no wonder, then, that research is aligned with the benefits that come with implementing SIP trunking in a communications system.
