[Serusers] Can't invite

[Rosa De Santis]

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
