There is a strange issue. I just compiled and installed asterisk 1.4 from the tarball. I have centos 6.4
I have also setup freepbx 2.9 on my box. I am on a Public IP and there is no nat.
Here is the issue,
I am unable to play any sound internally. I call the playback (hello-world), SayDigits(12345), try using a short code *65 to say the extension name. I see no errors on the console.
There is no audio at all.
Also, there is no issue when I try making outbound calls externally. I have no voice issues when calling externally.
What could be wrong ?
