Udit You can use c=IN IP4 0.0.0.0 to indicate hold in addition to a-sendonly.

So when UAS receives this SDP, it should respond with "recvonly" attribute. But same mechanism can be used by user agent if he wants to play announcement or music to user, so it can send "sendonly" attribute for media stream. I mean if it simply wants one-way connection (this is not hold). For 3PCC (as B2B), if it wants to provide MOH service, how can it differentiate between two SDP because it will play MOH only in the first scenario when user press hold. Is there any other way where user agent can indicate that this is hold scenario and not one-way audio.
