Hi,
>I think , the additional re-INVITE will solve the problem
>But as UE-B has rejected the re-INVITE obviously by 4xx, he/she doesn't need to send the addtional re-INVITE.
Well, THAT is the main issue we are discussion now, isn't it? Ie does the re-INVITE error response have an impact on the negotiated SDP (with preconditions met) or not.

Hi,
If preconditions are met for the video stream, but UE-B then decideds that he doesn't want to video, an alternative to "late commitment" is for UE-B to send a new re-INVITE/offer to UE-A and remove the video.
Regards,
Christer

Hi Gonzalo Camarillo,
If UE-A wants to communicate with UE-B by video, but UE-B only want to communicate by audio.
and if they uses the new SDP, when pre-conditions met, UE-B will send his/her videos regardless
of UE-B's willing.
And if UE-B never send his video although the pre-conditions are met, then UE-A will be puzzled why
he/she is charged for vedio while receiving NO vedio from UE-B.
I think this is a operational problem that we have to solve too.
regards,
Eric

No, if they negotiate video and the preconditions are met, they will be
charged for video, regardless of what happens with the re-INVITE.
Cheers,
Gonzalo
