[SR-Users] Transaction Lookup Failing

[Daniel-Constantin Mierla]

Hello,

if you run with debug=3, isn't there any hint in the logs from tm module
why the cancel is not matched to an invite?

If you want us to investigate, send the logs with debug=3 and pcap with
the sip messages for the failure case.

Cheers,
Daniel
