[SIP Beyond VoIP] Add participants to conference issue

[Ram Anji]

Thanks for the response.

In my case INVITE is not initiated to the participant from sylkserver.
That's the reason i am not added in the diagram.

Here I am enclosed the trace at sylkserver.


And Following is the SUBSCRIBE request and response. tell me what is the
wrong in subscribe request.
