audio problems

[Gary Vassalotti]

Hi All,

I am new to setting up the system.... I have setup PBXiaf on a raspberry...

It is setup, I have a Cisco 7912g phone that I have gotten to almost work. If some calls me there is absolutely no audio, if I call out, and the person answers, they can hear me, but I do not hear them.

I figure it is either a codec issue (I am using ulaw only, as recommended in other posts)., or a port forwarding issue. I have set they raspberry, at least temporarily, in a DMZ zone. I have forwarded the following ports:
5060-5061 Both protocols to my raspberry
300000-30020 UDP to the raspberry (another post recommended trying to narrow the port ranges)
and 10000-1020 udp, again to the raspberry.

My phone does register with Asterisk....

Any thoughts?

Thanks in advance.

10000-20000 UDP is what you need to forward, but all one way audio issues are firewall related. Double check iptables isn't causing a problem either, stop the service for a few minutes to test that theory out.
