Thanks a lot for your reply.
As per the RFC , I need to send the REFER to conference URI which I will get in contact header of 200 OK.
Conference URI should be different from Conference factory URI in INVITE request Line.
However from Sylkserver trace , both conference uri and conference factory uri are same.
INVITE sip:conference at 172.16.103.42 SIP/2.0
SIP/2.0 200 OK
Contact: <sip:conference at 172.16.103.42>;isfocus
Please let me know in case any configuration is required so that Sylkserver
should send different conference URI other than conference factory URI.

This is not needed.

This is the problem. Inviting participants must be done with an out of dialog REFER, as per RFC4579 (sec 5.5). In dialog REFER requests are rejected by SylkServer.
