Infonetics Research’s (News - Alert) new report “SIP Trunking Deployment Strategies: North American Enterprise Survey” shows that SIP trunking is becoming more popular.

 

The survey revealed that on an average the respondents spent between $100,000 and $500,000 annually on trunking services. Even though T1 lines are still the most widely used form of trunking service that connects to the Publicly Switched Telephone Network, the use of indigenous VoIP trunking service are growing in popularity. Thirty-nine percent of all survey respondents said they had already installed SIP trunking.

 

SIP Trunking is expected to become the second most widely installed trunking type by the year 2010. The survey noted that respondents were installing SIP trunking virally across their enterprises and not just as a test dose at one or a few locations.

 

 

The report -- based on a survey conducted by the agency that asked purchasing decision makers at medium and large enterprises about their usage of PBX (News - Alert) trunking services – is  part of the agency’s Enterprise VoIP and Unified Communication Continuous Research Service. Data is based on respondents’ answers to questions on the extent of their PBX usage, trunking services, providers and costs.

 

Infonetics Research polled 92 North American organizations with 101 or more employees that utilize PBXs, phone systems including private branch exchanges and key telephone systems.

 

Researchers sought to analyze why enterprise choose to install SIP Trunking and the main criteria used to pick an SIP trunking service. The report also looked to understand where and how SIP trunks fit in with current infrastructure and the resulting cost savings, if any.

 

“Many companies have already deployed VoIP internally, but they usually use legacy TDM technologies to connect to the PSTN. In our latest study, we finally see this changing: SIP trunking is catching up with TDM services and gaining broad traction with buyers, driven by their desire to lower their overall trunking expenditures,” said Mathias Machowinski, the directing analyst for enterprise voice and data at Infonetics’ Research. “However, SIP trunks are usually implemented during general technology upgrades, which are on hold at many companies right now.”

 

 

In conclusion, the survey gathered that most respondents have comprehensive information and knowledge about their enterprise’s PBX trunking services. The respondent also displayed influence over the planning and purchase decision making process for PBX Trunking services.
