	F3 should not have empty line in SDP between "t=3034423619 0" and " m=audio 3456 RTP/AVP 0"

Comment 3:
~~~~~~~~~~

Wouldn't it be better to send the "isfocus" re-INVITE to Alice after carol is actually conferenced in?
That way, Alice would not get the false impression if Bob aborts conference because Carol isn't answering. 

Comment 4: 
~~~~~~~~~~

Should Bob send a hold re-INVITE to Alice before he calls Carol?

Carol could have learned Bobs conference URI using some non-SIP means

F10 (200 OK Bob -> Carol) should contain "isfocus" in Contact.

Comment 5: 
~~~~~~~~~~
F11 ACK should be sent to Bob's contact "sips:bob-Mixer@...."
