Hi, I also had difficulties trying to figure out what you really want to say in the draft, but it seems like Paul has the same understanding as me: you do not touch the signalling related issues associated with hold, but only what local actions the UA should do when it is put on hold. Also, I believe there could be cases where you do NOT want a hold tone to be played. For example, if I put you on hold because you are going to be transfered to someone else, I don't think you want to listen to a hold tone while communicating with that someone else... Regards, Christer

We don't normally specify much about what the UA should do in those cases - the UA has latitude to do as it wishes, which provides room for innovation. Certainly a UA this is not receiving media is free to play something locally if it wishes. But some people would prefer not to have that. Also note that hold applies to any kind of media, not just audio. What to do with video, or whiteboard, or IM or realtime text will be different than what to do for audio. The issues that have arisen with hold have to do with people getting the signaling wrong - sometimes in a way that prevents getting off hold.
