Hey Guys,
I came in need to delay 200 OK sent to originator, I know that is not
the job of a proxy (not a perfect world though), so if anyone think
that should be in theory at least possible with kamailio/sr, I would
appreciate any tip.
Scenario: User A -> Proxy -> User B.
User B will send 183 and then 200 to the User A.
I would need to delay the 200 OK sent to User A with a number of
seconds, but still send ACK to User B to "fake" the receiving of the
message in time. When the ACK for the delayed 200 OK comes back from
User A, I would simply absorb it.
Would that be possible with kamailio/sr without using an external application?
delaying of any kind of sip message is possible with sleep() function
from cfgutils module. Beware it is blocking operation.
Sending ACK is not something you can do out of the box. There is
uac_req_send() from uac module, but it is about sending out of dialog
requests. However, writing a function for config to send in-dialog
request would not be that complex.
Cheers,
Daniel
