Hi, Ankur -

We use "a=sendonly" for sending Music-on-Hold.  There is no need to waste bandwidth on receiving.

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
