[Spce-user] [EXTERNAL] SIP Calls Failure with timeout on mr13.5.1LTS - Works on mr8.5.1

[Marco Capetta]

Hi,

I'm glad that the first problem has been resolved.

For the routing problem, it is really difficult to find the route cause
without any sip trace or logs to check.
What I can suggest to you is to double check that the interfaces and
sockets are properly defined in the configuration, and that peer/subscriber
are associated to the same interface and sockets.

If you could provide a SIP trace and a verbose log of the kamailio proxy
service, we could probably be more precise in the analysis.

Thank you
Regards
Marco
