Hi All,
I am executing the SIP to Mobile call. The complete scenario is as
below.
SIP(UAC) SWITCH
MS
-------------->
INVITE with SDP(precondition not met)
---------------->
PAGING
---------------->
SETUP
<---------------
183(Session Progress)
---------------->
Prack
<---------------
200OK(Prack)
Now Switch is waiting for UPDATE from SIP(UAC) for preconditions to be met. In
my Case UAC is not sending the UPDATE msg.
I want to ask is there any timer for UPDATE on UAS forreceiving UPDATE so that
it can release the call, because here the resources of SIP(UAC) are not getting
released till 18 minutes.
_______________________________________________
The UAS is required to send a 1xx response every minute. If the UAS does not
want to wait any longer for the UPDATE, it can reject the call with any 4xx
response. It can do that at any time.
