If A and B parties are communicating with each other and A wants to put B on hold it will send "SENDONLY" in INVITE
and B in response to it should send "RECVONLY".
After some time if in between of hold condition, B also wants to put A on hold then B will send "INACTIVE" in INVITE and in response
to it A will send also "INACTIVE".

Hi All

Can anyone explain why a=sendonly is sent in offer from side performing HOLD ?
I think a=inactive should be right way of holding call .
Any specific scenario which explain when to use sendonly and when inactive

Thanks & regards
