Many thanks for your answer... I am connecting on a Pfsense system from which behind is the Asterisk server and yes it has two network cards. I have all systems working with softphone from iPhone ie with openvpn client.

I tried the push route command from VPN server side and getting this error "May 9 20:38:41 openvpn[361]: ERROR: Linux route add command failed: external program exited with error status: 1" as you can see at the logs above... I will try to add also to vpn.cnf.

The strange thing is that I can ping the tunnel address of the phone (10.20.1.2) from the server and I can see from pfsense the try of the phone to connect to the server on 5060 port... (outgoing port from yealink is 5062).

i'll check your steps and come back with update.

P.S. Is there ANY way to have CLI access on the phone? it would be the best way to trace problems like this!!! (any serial port on the PCB board maybe also?)

Thanks!
