Hi,
I have the attached cpl script. It rings the IP phone
first, if not answer, then send to a pstn phone. The
script was working, but is broken now. I am not sure
if it is the script or any latest development breaks
it.
can you be a little bit more specific. what exactly doesn't work? is
some error generated?
a description of what happens and what should happen will help.
eventualy some logs also.
A couple of issues,
If the call is canceled when still ringing ip phone,
the call is forwarded to the pstn phone. So pstn phone
rings for nothing. It looks like cancel didn't cancel
the original transaction in cpl.
it's interesting. anyhow, CANCEL is not process by cpl. CANCEL should
match the INVITE transaction and cancel all active branches. What can
happen is: if you do a proxy and if fails (negative reply) you do action
X, when you cancel, we will receive 487 which will be consider by cpl a
negative reply for the INVITE and it will do action X. For me is perfect
logic. Be sure that this is not your case.
A brand new call... If the call is sent to PSTN phone
eventually, PSTN phone picks up. But didn't hear
anything, the original phone still hears the ringing
until a few seconds later. Then they can talk.
again, interesting;; watch the signalling - my guess the reason is some
delay in signalling because of GW??. Do on your server a ngrep/tcpdump
with time stamp and see who's guilty for delaying.

bogdan
Thanks for your help in advance.
