The SIP Survey recently published its eighth-annual SIP and Cloud survey, and as I looked over the data I expected the results to demonstrate a decrease in provider problems -- my expectation being that SIP trunk implementations would have become a commodity installation. Not so.
For its 2018 SIP report, The SIP School gathered input from 840 respondents. It collected and analyzed the data throughout most of fourth-quarter 2018, releasing results earlier this month. The graphics in this blog are from the survey report.
Providers, Top of the List
SIP trunk providers continued to be the source of most problems in 2018, although the issues did improve slightly. In the survey, 32.73% of respondents reported experiencing problems, down from the 36.73% and 33.63% who did so in 2017 and 2016, respectively. (I’ll cover equipment vendors in my next post).
Respondents who reported that they have “Never had a problem” attributed their successes to good planning, thorough testing, training, and good support from the providers themselves. These seem basic best practices, but the survey found that 20.28% of respondents never performed SIP trunk service trials prior to implementation. Not a good idea.
