SDK to build VoIP Conference Call Support

Archived from groups: comp.dcom.voice-over-ip (More info?)

We would like to build a conference call solution for VoIP where people will
connect using SIP phones. Has any one done this, is there any tools
available. I saw a solution from
http://www.sysmaster.com/p_vp_conference.htm but we would like to build our
own since we need some advance functionalities like call recording etc.

I Forgot to also mention that you get other example applications with
source code too.

Using the VOIP media engine will greatly simplify your development
task. It interoperates with many, many other SIP applications and
devices such as SER (iptel's sip express router), Cisco's sip proxy
server, Pingtel, eStara and Xten SIP apps, just to name a few.

Thanks.
