[OpenSIPS-Users] MediaProxy as bridge between Private and Public Interfaces

Hi All,

 

I have MediaProxy working in a multi-homed setup where it is acting as a
relay between an interface on a public IP and one on a private IP (We
connect to our SIP provider over a private network via the private
interface using static routes in the route table, and a SNAT out the
private interface)

 

The system is functioning and calls are being relayed between public and
private interfaces, however with every call, I am receiving the
following in the logs (which is a bit unnerving):

 

Feb  3 15:19:32 SIPProxy1 media-relay[6806]: Traceback (most recent call
last):

self.callee.remote, self.callee.local, self.stream.session.mark)

Feb  3 15:19:32 SIPProxy1 media-relay[6806]: Error: No such file or
directory

 

I have tried strace to determine what file may be missing or lacking
permissions, however there are references to hundreds of files and it is
proving difficult to track down.

 

Has anyone seen this before, or could suggest some other way of
troubleshooting the issue?

 

Many thanks,
