[OpenSIPS-Users] B2BUA Mangling Messages

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
