Hi Ankur,

a=inactive is used when the user wants neither to send data or receive any data on its port. By a=sendonly, user means that "I would not like to receive any media from you" and asking the other side to keep quite but it can send media. This is the main difference between inactive and sendonly.

Thanks & regards,

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
