<html><body><div>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?
