Windows Messenger does not create a ringback tone. I don't know the
behaviour of SJphone as I never used it. But I can recommend x-lite
which generates local ringback.
The warning header is nothing to worry about - it's just for debugging
purposes (IMO very useful). You can turn it off if you like
(http://iptel.org/ser/doc/seruser/seruser.html#AEN709)

If a 183 Early media is received, the callers UA will use the incoming
RTP stream as ringback tone.

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@192.168.68.20
out_uri=sip:shiva-smarttest-com@192.168.68.20 via_cnt==1"
I am attaching the relevent parts of the ethreal trace with this.
Thoughts?
