Benefits of SIP Trunking

SIP trunking is the heart of what makes your VoIP system talk to the outside world, or the Public Switched Telephone Network (PSTN). There are alternatives, including using a hosted VoIP environment, and deploying PRIs (Primary Rate Interfaces), or of course, just using the Public Switched Telephone Network (PSTN) and not using VoIP at all. However, VoIP delivers so many advantages in terms of cost and extra features, many enterprises are finding it to be an essential component of their telecommunications environment. As such, SIP trunking is often a major consideration when an on-premises VoIP deployment is made.

When compared to a conventional analog circuit, SIP trunking affords the same level of quality at a much lower price per circuit. Further, when compared to PRIs, SIP trunking affords a similar price performance advantage. PRIs must be purchased in combinations of 23 channels, whereas SIP trunks are purchased incrementally, which gives the enterprise a great opportunity to purchase only as much as is needed.

Deploying SIP Trunking

When deploying SIP trunking, it is not necessary to purchase a SIP trunk channel for every extension, rather, only enough to accommodate simultaneous calls. For example, if an enterprise has 100 telephone extensions, but at any given time only 25 people are on the phone, then only 25 SIP trunks are necessary to accommodate normal traffic. Some oversubscription to that figure would be a wise investment, but even with oversubscription, SIP trunking affords a much more efficient use of resources.

Scalability is also an issue with any telecommunications environment, and SIP trunking allows for easy additions. When additional extensions or higher phone traffic demand more SIP trunks, they can be purchased incrementally, one at a time, on an as-needed basis. A PRI solution on the other hand, has a 23-channel incremental purchase requirement, which may mean that businesses would find themselves buying more channels than is really needed. Another comparative advantage between SIP trunking and a PRI solution is implementation time; a provider may require as much as 30 days to provision PRI channels, and it requires an on-premises visit; whereas SIP trunking can usually be rolled out remotely within 24 hours with no truck roll required.
