Hi,
I have SER and 2 cisco SIP phones. When I call between the SIP phones, I can hear
voice from only direction (callee to caller works, caller to callee doen't work). Both
phones display connected in their LCD screen and I also checked the codecs used by the
phones are same. I would appreciate if anyone can point me what is wrong and what are the
possible solution to this problem.
I have attached the ngrep output below. In the second message of the output, I can see
a "Warning: 392" header field with a value "Noisy Feedback tells:...".
ngrep output:
------------
interface: eth0 (192.168.6.0/255.255.255.0)
