2. reinvite
Secondly,
when opensips is used as b2bua scenario as below
A opensips B
-> invite ->invite
<-200 <- 200
-> ack ->ack
... ....
<-reinvite for keeeping session alive.
Is there a way that I can let respond opensips 200 OK on the reinvite without forwarding the request to A ?
so I want
A opensips B
-> invite ->invite
<-200 <- 200
-> ack ->ack
... ....
<-reinvite for keeeping session alive.
->200
instead of
A opensips B
-> invite ->invite
<-200 <- 200
-> ack ->ack
... ....
<-reinvite for keeeping session alive.
<- reinvite
-> 200 ->200
wkr,
