I am having a great deal of difficulty with one particular ITSP and it seems only on the UC-500, not getting the same issue with a 2800 series setup at all.
The UC-500 was configured using CCA, and the other systems this SIP account has been used on have all been installed via CLI, this is so far the major difference i can find between the devices, however i am not sure what CCA puts in place to make SIP trunks not work off the bat.
The issue is that i can not establish an outbound call, i am not overly intersted in the inbound at this stage, but primarly the outbound calls, previously Dave Harper assisted with this, however the problem has rared its ugly head again, but this time nothing is working to resolve the problem.
In the attached Debugg i see a bad request there, however i am unable to work out exactly what this is for, i have also worked on the Voice Class coded to use the preferred Codec that MNF use (G729br8--- Which i don't know why), and i have made sure that all the dial-peers are correct.
The thing is, if i remove it and use one of our other SIP trunk providers, it fires off straight away.
Any suggestions would be much appreciated, i have looked over the debug file so much i think i just need a break from it as i am cerain i am missing the most smallest of details that is causing the problem.
