I have a basic configuration with SIP provider via eth 0/1 and a PRI connected with a PBX.
The unit is installed behind a NAT router with the public IP 108.X.X.X.
I can't receive incoming calls and in debug I get:
12:50:10.688 SIP.STACK MSGSUM Tx: REGISTER sip:64.XX.XX.XX:6060 SIP/2.0

I can make outgoing calls.
