Netvanta 6310 goes to one way audio after 5:13 on internal calls
We have a Netvanta 6310 that is deployed. When internal calls are made in the BG the call will go to one way audio after 5:13. On the Adtran we have the Sip ALG disables. Are there other settings I should look into that may be causing this. It seems like something is causing a pin hole?
