Hello all.

I'm new with this and I'm making test with 3 machines in the same network using SER-SEMS. I receive the REGISTER messages from the users, but I can't make an INVITE from one user to another.

I've tried with stateless forwarding, with no result. Please, some help needed. Could anybody tell me what's missing or wrong ?

This is the ser.cfg that i'm using.

Thanks in advance Ro
