I have an Asterisk@Home installation in my organization. I have had this installation for more than 3 years but never noticed this problem. There are 2 problems, but both seems to be related. My SIP extensions have one way audio
-
SIP extensions have one way audio; others can hear them but not vice-versa. No, this is not a problem with one desktop. This is present in all desktops where sip devices are installed. This is true for ZAP trunks as well; but it does not look like a firewall problem since the problem exists for calls between 2 extensions.
-
SIP extensions do not ring. However, you can make outbound calls from them and the called party can hear them but not vice-versa.
My IAX extensions seem to work fine. Here is the log when an IAX extension makes a SIP call

Please note the message “Methodology of ring is ‘none’” and the lack of message “Extension 20001 is Ringing”.
Any help will be appreciated. The Asterisk version is 1.2.7.1
