Are you starting SER in non-forking mode? It looks like SER is not binding to the 10.10.10.41 IP, only to the local IP (127.0.0.1) and that's why you see in the logs that it's not able to send to a "standard" IP address: WARNING: xl_mod_init: more IP 10.10.10.41 not used CRITICAL: invalid sendtoparameters one possible reason is the server is bound to localhost and attempts to send to the net

Case you need to use 2 interfaces, I would recommend using mhomed=yes (don't recall the exact syntax right now..).

Hope it helps, Samuel.

Hi All,

This ser installation was working fine and I can't figure out why its not working now. I'm getting an error (see last log line) every time I attempt a call to local users. Calling out to PSTN works great. ngrep reveals that SER is not sending any messages to the callee location.

There are 2 registered local users, one registered twice.

I have no idea what is going on. I'm using an unmodified version 1.4 ser.cfg file on CentOS 5.

I suspect some server configuration error? ? ? ?

Thanks, M

Here are the logs.

When I start SER I get this response:
