The SIP Survey 2011

April 6, 2011

In February, The SIP School in association with Techistan carried out a survey to find out what's really happening in the world of SIP and SIP trunking.  In fact we wanted to see what problems people were getting and work out what people need to do in order to get SIP Trunking right the first time.  

We found that problems ranged from Codec issues, No - Audio, Failure to keep systems patched, Call transfer issues and many many more.
