Hi,

We are developing a third party call control application where we have to reconnect \
two parties A and B which are in the hold state  i.e. party A and B had received \
IVITE with a=sendonly in SDP,

We know the SDP of both the parties A and B (i.e the RTP ports where they are \
receivign the media streams), my reqmt is to connect parties A and B.

One method is :
i) Send INVITE (with B sdp, a=sendrecv) to party A
ii) Recv 200OK with SDP of A 
iii) Send INVITE (with A sdp, a =sendrecv) to party B

But problem will be that the SDP recvd in 200 OK frm party B can be diferent from the \
earlier one, so I need to reconnect them again.

I want to knwo by which we can we can reconnect both the parties and they know the \
SDP of each other also.
