Subject: [Sipping] Doubt in offer/answer model

Hi all,

Consider the following case in offer/answer model.

One UA supports an audio and a video while the other UA supports only
video
After negotiating, should the reply sent be 606- NOT ACCEPTABLE response
code with "WARNING" header telling media not accepted ?

If so, should ACK be received for 606, ie. for each negotiation should
ACK be sent?

Regards.
