[ABN] I am not very sure we can reject the call on hold or not since the call hold request would have the same set of codec's/other SDP parameters which for other party would still be acceptable... > 3..

[ABN] if at all this is possible, the 488 would not have any impact on the existing call. The call would still persists further... > 4..
