Yes, since we are doing this as part of the educational programme, and
more over we plan to take special permission from BSNL towards this.

Could you please explain me how does this soft PBX works ? and I want all
the functionalities of the sip.

Since ASTERISK does support SIP also. I think it should be ok to use
linphone,gnuosip,partysip. because gnuosip provides a set of API's which
these software will use.

Asterisk may not use that since it already has sip stack.


But i think we should take care of ports

Yes, want to use it on the same machine,as you said, i really dont know
whether the asterisk sip stack and gnuosip will collide......definetly.
