Hi,
I had the same problem. In my case I was testing with one user agent
behind NAT and the other on a real ip. I wonder whether it's the same
situation with you as well.
Hi,
I have SER and 2 cisco SIP phones configured. When I call between
the SIP phones, I can hear voice from only direction (callee to
caller voice works, caller to callee doesn'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 where this gets wrong and what are the possible solutions for
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)
