Hi, I would like to know whether this conference call flow is a standard way of implementation.
A---> B Call Established A----> hook flash dial C A ----> hook flash (Is the hook flash on A in that state is allowed to enable conference ? ) A & B should hear the ring back. Could anyone point whether this call flow is valid ? -Anand _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
