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)

The ringback tone is generated locally by the callers user agent - typically as soon as the 180 ringing is received.
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?
