Birmingham, United Kingdom, May 25, 2012 --(PR.com
)-- With a rise from 400 to 500 on last years respondents and a few new questions they aimed to take a look at SIP Trunking and specifically, to find what the most common issues during SIP Trunk deployment are and what can be done to make these issues occur less frequently, if at all.
There are some great numbers to check out such as:
55.5% or respondent companies are using SIP trunks now
70% have a VoIP PBX as their main PBX
Avaya leads the manufacturer list
Acme Packet is top of the SBC list
Most problems reported last year are still occurring
Yet support seems to be getting better from most companies
Also, Fax seems to be requested more than HD voice
There is a lot of interesting stuff in this document along with comments from experts in the SIP trunking "space."
