Hi Manoj,
To hold a call, UA should send the SDP in INVITE. Other party can put the call
on hold based on media change in SDP.
If SDP is not present in INVITE, other party must send the SDP in 200 OK as a
new offer and UA should send the answer SDP in ACK.
Thanks,

Dear All,
If a particular UA sends and INVITE to hold a call, do we have to
include SDP?
If SDP is not included in the INVITE, Should the other party include SDP
in OK message?
Thanks

You should tell the phone vendors to do a better job of implementing REFER.
What do they do? Just send a BYE on their own call as soon as they
receive a 2xx for the REFER?
If you *really* want to make it work despite the behavior of the phone,
you might consider:

Sagar,
Think of it like declarations in nested scopes in a programming language.
The outer (session level) scope applies except where overridden by a
redeclaration in an inner (media level) scope.
This applies to a lot, but not all, attributes. (The ones that may be
used at "both" session and

Hi Sagar,
As per offer answer RFC the attributes at Media level will be taking preference
than at session level.
So in this case wither Video will be Send Recv and Audio will be mute or other
wise depending upon the "a=" attributes in individual Media streams.

Frank,
Yes it is perfectly normal. But what I am trying to understand here is...
Consider a video call which have 2 stream, one for audio and one for video.
each stream can have its own attribute("a") with direction values (one
having sendrec and other is inactive).
"a" is also present at session.
Yes You are right. I mean it for this particular case. Sorry for confusing

"a" means attribute and it's used for more than just the direction of
the stream.
