hi, thanks for your response.
is the sending of CANCEL handled by the openser engine internally? i need to do
this from the openser config file. basically, my statement is like this:
onreply_route[2] {
if (status =~ "(183)|(2[0-9][0-9])") {
if (client_nat_test("1")) {
fix_contact();
append_hf("P-hint: Reply applied\r\n");
}
use_media_proxy();
}
if (status == "200") {
invoke_my_function_from_here("$fu:$tu:$ci");
if (retcode == 1)
{
# propagate OK to caller; do nothing
}
else
{
# terminate or cancel INVITE from here
}
}
}
i should also be able to do this in proxy1 from the figure below. i think i
need to send CANCEL to UAC1 and BYE to UAC2. this is my understanding of the
RFC. someone may have implemented a function or module to handle this. thanks
again.

When you get 200OK, you send an "ACK", so it is a good indication for the
initial "INVITE" that it is ACKnowledged. When you get an error, anyway you
will not send "ACK" instead still send the "CANCEL" so the UAC2 is clearly
handled (and it will not wait for ACK), give a try !!!
Thank You,.
With warm regards,

Subject: [Users] cancelling INVITE during OK response
hi, is there a way to cancel or terminate an INVITE or call upon receipt of
the OK reply. my configuration invokes an external program which either return
success or failure for OK message (response to INVITE). when failure is
returned, i want the script to terminate the call or cancel the INVITE (OK
message will not be forwarded to the calling UA). is there an existing
function or module to realize this? the scenario is drawn below with
provisional messages removed.
UAC1 ------------------ proxy1 ----------------- proxy2
--------------- UAC2
call:
INVITE
---------------------------> INVITE
---------------------->
INVITE
----------------->
OK
<----------------
*XXX
-
error occurred
during processing
OK message
thanks,
sho
