[OpenSIPS-Users] Conferencing

[P.K. Kapila Susantha]

Hi,

I am new to open phone. I configured a opensips server by following the
steps in "Building Telephony Systems with OpenSIPS 1.6.pdf"
documentation. I have already built an end-point using Open Phone pilot project.
It works fine in a VPN as peer to peer (without going through the SIP
server) with 2 users.

Now I would like to implement conferencing capability into this end-point.
Can someone please tell me the documentation I should follow for this
and what are the challenges of implemeting conference facility with SIP?

regards,
Kapi
