Hello!
When i'm trying to call from UA to PSTN i have a call failure after 40 sec. All my
UA's (private and public ip) works fine when calling each other. Calls from PSTN
---> UA's also works fine. But when i'm calling to PSTN i may talk only 40 sec.
I'm tried from NAT UA's and UA's with public ip, softphones and ipphones -
same result. I don't know what to do, someone please help me.
UA (Sjphone) - 192.168.97.88 (symmetric nat) - 211.211.211.211 (outside ip)
Openser - 212.212.212.212
PSTN Gateway (Alterteks CallSwitch)- 213.213.213.213

The ACK was not dropped because the UA was broken, but nevertheless you
the UA didn't properly handle record-routing.

The ACK was not dropped because the UA was broken, but nevertheless you
the UA didn't properly handle record-routing.

In general ACKs and CANCELs must be treated like the INVITE when request
uri's are rewritten.
This means that if you rewrite the uri in the INVITE in the PSTN case,
you must do the same for ACKs and CANCELs (but don't challenge/auth. them!).
What happens in your case is you send an INVITE like
91234@ser_ip which gets rewritten to 9123@pstn_ip by ser and forwarded
to the pstn gw. When the pstn replies it sets the Contact to the ser ip
(91234@ser_ip). Now when your UA sends the ACK is sends it to the
Contact in the 200 Ok, so it will send and ACK to 91234@ser_ip. However
in your ser cfg the ACK is handled differently and the uri won't get
rewritten to 91234@pstn_ip. The ACK will be forwarded untouched
instead, which results in a loop (it will be forwarded to ser_ip).
You will have the same problem for CANCELs (you won't be able to cancel
a call to the pstn).

New subject: Re[2]: [Serusers] Strange problem - SIP-->PSTN - 40 sec calls duration
Huge thanks, all is clear for me now!
i'm solved the problem, which was in pstn gateway (auth incoming calls problems and
(404 - user not found) replies in packets on it).
script is right.
thanks one more time, Andrei!
