Hi, A couple of questions regarding the usage of the more-coming flag: Q1. If one sends an ANSWER with the more-coming flag set to 'true', is it allowed to later send *additional* ANSWER(s) with the flag set to 'true' (before sending the final ANSWER)? Q2. Are there restrictions when it comes to changing information in a non-final answer and a final answer? Or, can the final answer be completely different from previously sent non-final ANSWERS? In "legacy" O/A there are restrictions. Q3. Must the answerer wait for OK for a non-final ANSWER before sending a new ANSWER (non-final or final)? Q4. If the answer to Q3 is "no", how does the answerer know to which ANSWER an OK message applies? AFAIK, the seq/sessionId values are identical for all ANSWERs associated with a specific OFFER. Q5. The text says, that while the OFFER is "open", ie a final ANSWER has not been sent, the answerer is not allowed to send an OFFER. I assume that also applies to the offerer, ie it is not allowed to send a new OFFER until it has received a final ANSWER - even if it has received one or more non-final ANSWERs. Maybe it's obvious, but I think it would be good to explictily add some text about that (if my assumption is correct, that is :).
