[asterisk-users] Testers for ISDN AOC (Advice of Charge (Gespraechsgebuehren)) needed

[Klaus Darilion]

Hi!

We have implemented AOC-D and AOC-E passthrough support for Asterisk 
(both Asterisk 1.2 and SVN trunk). Currently this works only with ZAP 
PRI channels.

With this feature Asterisk forwards AOC messages received from the telco 
switch on bridged ZAP PRI channels. This is very useful, if Asterisk is 
between a legacy PBX and the telco line.

There are 2 patches: one for libpri and one for Asterisk

You can download them from
http://bugs.digium.com/view.php?id=7494 and
http://bugs.digium.com/view.php?id=7495

Note: You have to activate AOC processing with "allow_aoc=1" in 
/etc/asterisk/zapata.conf

;
; Asterisk supports basic AOC (Advice-of-Charge) forwarding (zap2zap).
; By default this is turned off. The AOC forwarding is designed for
; Asterisk installations where the Asterisk is located between a PBX
; and the telco line.
;
; The AOC-implementation status is:
;   AOC-S (start): not supported
;   AOC-D (during): supported
;   AOC-E (end): partly supported (fake AOC-E)
;         - If the telco switch hangs up first, Asterisk will forward
;         the AOC-E message when sending the DISCONNECT message to the PBX.
;         - If the PBX hangs up first, Asterisk will take the last received
;         AOC-D message from the telco switch (if available) and send it
;         as AOC-E message to the PBX in the RELEASE message. Thus, this 
AOC-E
;         message is a "faked AOC-E" and may be inaccurate.
;
; Note: The AOC message will be inacurate if you perform certain 
functions on
; the bridged calls, e.g. call transfer, ...
;
;allow_aoc=yes
allow_aoc=no


Please test it and let me know how it works.

Thanks
Klaus
