[OpenSIPS-Users] B2BUA Mangling Messages

Mon, 05 Dec 2011 11:53:41 -0800

Hello List, I'm implementing the B2BUA module in the default Opensips config file to play with it. I'm seeing some oddities with it's processing of cancel messages. I'm including a trace of the cancel flow. It looks like the B2BUA is adding a bunch of "......." and other characters in the message. Has anyone seen this before, or help me figure this out?

Reference:

192.168.1.146 = Opensips Proxy
192.168.1.145 = Opensips B2BUA
10.2.3.245 = Carrier
