SIP TCP + nat = yes + Polycom 550


#1

I’m using Asterisk 1.8.5.0 and I’m trying to use TCP instead of UDP. I’m able to sucessfully register my Polycom 550 if I have nat=no. As soon as I use nat=yes, by peer become unreacheable. If I fallback to UDP everything is working as expected.

I have theses error after turning nat=yes while in TCP :
