receiving
200 OK from destination but you must discard it if CANCEL comes from =
caller
instead of ACK. In fact i have seen some billing systems that actually =
start
billing upon receiving ACK from caller, rather 200 OK from destination. =
To
overcome the loss of few seconds (between 200 OK from destination and =
ACK
from caller), they use a different billing head called "connection =
charges".

Thank you.

This may work, only if you create dialog with 'B' flag, also 3 seconds =
look
very short, destination must be very quick to ACK the call.

I think there is a better way to achieve this, you only need to ensure
CANCEL is received at destination.
Thank you.

Hi ,

I face a lot of scenarios where the customer send a cancel while the =
trunk
send 200 OK and start the billing from its side ,so the client call will =
be
canceled from his side and goes to the max call duration from my side =
and
trunk side .
Si I draw this function below=20
loadmodule "dialog.so"
modparam("dialog", "timeout_avp", "$avp(timeout2)")
=20
if (has_totag()) {
if ( is_method("INVITE")) {
$avp(timeout2) =3D 3;=20
} else if (is_method("ACK")) {
$avp(timeout2) =3D 3540;=20
}
=20
Do this function effect on my calls or cause any problem
