Hi, I have a question on the usage of hold SDP that uses a=sendonly. Let's suppose User A is talking with User B. User A wants to put User B on hold and call User C. To place User B on hold, User A sends a re-INVITE with hold SDP to User B. Here, is the sending of the re-INVITE with hold SDP mandatory to place User B on hold? Another way could be that User A not send the re-INVITE to User B, but just drop the RTP packets received from User B. I can see that we save bandwidth by sending the hold SDP; is there any other reason?
Thanks, YoungSun _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
