Hi all,
 
one question on sec 5.3. Hold and Resume of media
 
"If UA2 has previously been "placed on hold" by UA1, via receipt of
  "a=sendonly", then it may initiate its own hold by sending a new
  offer containing "a=sendonly" to UA1."
 
From RFC3264 sec 6.1 Unicast Streams
 
  If a stream is offered as sendonly, the corresponding stream MUST be
   marked as recvonly or inactive in the answer.
 
so UA2's stream is either recvonly or inactive now.
 
And From RFC3264 sec 8.4 Putting a Unicast Media Stream on Hold
 
   If the stream to be placed on hold was previously a recvonly media
stream,
   it is placed on hold by marking it inactive.
 
So RFC3264 says it only could be inactive, why draft above says it may
hold with a=sendonly?
 
Thanks

Regards,
Rockson Li
