Thanks for the suggestion.
I tried to setup a pjsip trunk as suggested but I am unsure of a couple of things.
1. Am I correct that the match line is supposed to be a list of ip addresses for callcentric hosts? If I put a comma separated list of ip addresses for callcentric in the match box the list gets truncated. Apparently there is some unspecified limit on how long that line can be. If I put too many entries in the match line I get a list of ip addresses in pjsip__50-1-trunks.conf that ends with the following
2. In the advanced tab for the pjsip trunk there are no NAT settings.
I have Force,Comedia set in the network setup as suggested in your article. Is that what you are referring to?
I have never setup pjsip trunks before so I am unsure exactly how to do it.
Is there an equivalent pjsip command to sip show peers? I have not been able to find it of there is.
