[SIPForum-discussion] Call hold scenarios

[Paul Kyzivat]

The examples you show are all fine. It depends on how you want hold to work.

The key is that your offer should only consider your own needs, not your 
belief in what the other end wants. If you want sendrecv, then offer 
that, even if the other end has previously indicated something else. If 
you want sendonly or inactive, then offer that. The other end will deal 
with its needs in the answer.

Also, receiving an offer with sendonly or inactive does not necessarily 
mean you are being put on hold. It might mean that. It might mean 
something else. You can't really infer *why* it was offered.

	Thanks,
	Paul
