No, A is not on hold. Placing on hold requires a user action. Unless the user 
of A placed it on hold, A is not on hold. Anything done by B doesn't affect A 
hold status.

But you could argue that also A is on hold after  “3. A sends 200 ok with 
a=inactive”  ?

A should respond with a=sendrecv. The A response (offer in 2XX response to a 
re-INVITE) should depend on A hold status only. The state of B has no effect on 
A offers. So, since A is not on hold, a=sendrecv is the most appropriate answer.

On the other hand, if A sends a re-INVITE without SDP to B, B should respond 
with a=inactive, since B is on hold.

Hi !

A question that I hope is simple for some helpful person to answer:

1. Call connected between A and B
2. B holds the call with re-INVITE a=inactive
3. A sends 200 ok with a=inactive
4. B sends re-INVITE without SDP

A should answer a=sendonly or is a=sendrecv normally a better option or perhaps 
something else ?
