Previously, I made a push to demonstrate that SIP Trunking was moving beyond Early Adopter towards Early Majority. Several facts point to the increasing demand and shorter buying cycle. Before the end of 2015, SIP Trunk sales will exceed T1s, with Infonetics reporting that 58% of the 300 companies surveyed plan to purchase SIP Trunks (versus 55% buying T1s). Granted the percentages are close, and probably within the margin of error, but the difference represents a significant trend in the adoption of SIP Trunks over the last few years.
SIP Trunks deliver so many more benefits than T1s, plus they support call/contact centers and Unified Communications much better.
In the spirit of infomercials and “But, Wait! There’s More!,” please accept this second blog on the value of SIP Trunks. I ran across a blog by Dan Jacobson, which was of interest to me not because he used that famous (or infamous) infomercial phrase, but because he was discussing a white paper issued by Ovum earlier this year about the second wave of SIP Trunking. Given my attempts to defend the mighty SIP Trunk and position it as a tactical decision in migrating to Unified Communications (UC), finding this white paper was timely.
Ovum took the position that SIP Trunks had a greater value proposition than the obvious cost savings they provide over PRIs and services offered over TDM facilities. Some of the things included in their list of “second wave” capabilities have been products for a while, such as:
- Dynamic load balancing to support multiple contact centers, organizations or corporate communications entry points
- Business continuity with multiple SIP Trunks offering everything from failover or automatic call forwarding to mobile phones or alternative DIDs if the IP PBX, IAD or media gateway cannot be reached
However, Ovum knocks the ball out the park with the rest of their observations.
- Consolidating data centers or major infrastructure locations
- Audio conferencing savings, especially for multi-national companies
- Consolidating email services and email servers
- Platform/protocol for the integration and addition of UC services (e.g. IM, presence, video, conferencing and FMC)
Ovum’s SIP Trunking: The Second Wave Benefits is one of many articles presenting additional value propositions for enterprises considering a migration to SIP Trunks.
Finally, I also enjoyed SIP Trunks and UC: Take Another Look, by Lisa Pierce. In addition to promoting Unified Communications as a Service (UCaaS), and hosted offerings in general, she reminded me of a point I often forget to make when discussing SIP Trunking benefits: SIP Trunks are a secure, enterprise alternative to MPLS, and can perform session control for all real-time applications.
Although both of these articles are a few years old, they demonstrate why SIP Trunks are beating PRIs and T1s today.
