Thanks for the reply. The user agent is getting the 180 ringing, but it does not generate
the ringing tone. I have tested it with SJphone and another softphone which is built
using Windows and RTC, but both behave the same way. I have captured the SIP trafic using
ethreal and did not find anything weird. However, i am curious about one of the lines in
that trace:
Warning: 392 192.168.68.20:5060 "Noisy feedback tells: pid=23603
req_src_ip=192.168.68.16 req_src_port=5060 in_uri=sip:9000 at 192.168.68.20
out_uri=sip:shiva-smarttest-com at 192.168.68.20 via_cnt==1"
I am attaching the relevent parts of the ethreal trace with this.
Thoughts?
Regards, Girish
