I’ve got a SPA504G with Asterisk PBX and broadband.com SIP service. I can recieve calls fine on the handset, but when I make outbound calls, about half of the calls have one way audio or no-way audio. When I have audio problems, I can hit the hold button and then imediatly take the call off hold and that usually solves the audio problems.
The phone HW ver, is 1.0.3 and SW ver. 7.5.1a.
I have tried putting G729a as prefered codec and ulaw as secondary, and also ulaw prefered and G729a secondary, makes no difference.
