Hi Everybody,
I have small doubt regarding turning off the timer for provisional
response.
UAC UAS
| |
| ------- INVITE-----------------> |
| | ( No 100 Trying ,
directly 180 / 183 )
|<--------183 Session Progress--|
| |
In this case even after receiving 1XX response UAC does not turnoff the
timer kept for Provisional response for Invite.
1. Is it mandatory to send 100 Trying ?
2. 18X doesn't solve the purpose of 100 trying. In what all scenarios it
is mandatory.
Needs your comment.
Thank you
Have a nice day !!
Ankit Bhandari
