Hello,

which version of Kamailio do you use? In older version there have been some problems which are fixed now.

Generally speaking, the more complicated (like number of interfaces) your setup is, the more difficult it gets for Kamailio to pick the right interface.

You could of course always use the manual way with $fs and other methods.

Cheers,

Henning

Subject: [SR-Users] mhomed not working for tls destination

Hello,

I have faced an issue when mhomed parameter working well only for udp destinations in systems with multiple network interfaces.

If kamailio forward call to the UDP destination, mhomed option chooses the correct Via and the correct network interface for sending.

But if the destination is tls, mhomed chooses first described in configuration file "listen=" interface and use this IP in Via header

Network routes in the system are correct and "ip r get IP" returns the correct route and interface.

Should mhomed work with tcp/tls or is this impossible with TCP design?
