Hi there, Wonder if anyone can help me troubleshoot a one way audio problem.
First of all, everything works fine with Bria - I can call anywhere in any direction. The issue happens with Polycom IP450 phones. The setup had been working fine for weeks and weeks. Then one day, sound seems to progressively degrade when making outgoing calls. After a while, boom, the receiving party of calls originating from the IP450 hears us but we can't hear them. The problem lasted about 36 hours the went away on it's own or I am not sure what i did to make it go away. Now, two weeks later, this has happened again. I have updated the IP450 to the recommended version on the wiki. I have traced and traced. It does not seem to be a firewall/nat/helper issue as a) Bria works fine on the same subnet b) doing port copies on my switch, I can see the packets being sent to the hardphone. >From my limited but growing understanding of SIP calls, the server -> phone >direction seems doubled (though it might just look ok to me…). I can't hear a >thing and the diagnostics / media statistics on the phone increment in the >outgoing direction but not in the incoming direction. Anyone have any idea that could help me pin this down ? Might it just be a phone firmware issue ? I have supporting material if that can help.
