No Audio on Outgoing Calls - VOIPO
https://www.voipo.com/forums/showthread.php/52522-No-Audio-on-Outgoing-Calls
Re: No Audio on Outgoing Calls. Hope Tim can help out here... I've spent most of the morning rebooting and checking the HT702 ATA and my router to try to eradicate the outgoing call problem.

No audio on incoming calls - VOIPO

VoIP without audio is a NAT issue. If they connect then SIP signaling is working, generally on port 5060 or 5061. If there is no audio then RTP is not working. Check to be sure that SIP ALG is turned off in your modem. That's generally the best place to start.
