I have been trying to get a Grandstream HT814 to communicate with Sonetel. It works fine when connected directly to the DSL line, but as soon as I put it behind the firewall it stops. It cannot make calls, when receiving a call it will ring, but with no sound.

I have tried with the SIP inspection on and off (in the config below it is disabled)
