Hi Bogdan, Thanks for the answer. I tried this module, but nothing weird was found. On reply ACK messages in sngrep capture I see the correct "To/Contact'' header, but in log the "To" header looks different, but it's not lead to any loop.

____________________x_____________________________x_____________________________x_____________________________x_________ If I disable trace("tid", "d/t/m", "sip") module at route level, I never faced with loop.I also found that trace("tid", "m", "sip") is worked for specific messages, f.e INVITE, and not looped too. If I have something wrong with the route, it should also be looped without enabled trace(), but it's not happen. I think it's around the rules of trace() module and rules there this module may be enabled. Maybe you have an example for enabling the trace() module globally?
