asterisk users - Dec 2007 - Any idea how making Asterisk "transparent"?

Hello!

I am using Asterisk as transparent voice recorder for calls (isdn <->
asterisk <-> pbx). Voice recording (therefore voice forwarding) is
working great but seems that Asterisk does not route/bridge/forward
D-Channel messages which means PBX cannot get time synchronization
answer from provider and tarification impulse too. With direct
connection PBX works great and use both synchronization and give
impulse value so there must be problem on Asterisk side.

Machine is using lastest versions of Asterisk 1.2 branch (at time of
writing: zaptel 1.2.22, libpri 1.2.6, asterisk 1.2.24) on Fedora Core
4. I tried with facilityenable=yes as well without success. I do not
exactly know what facilityenable for.

Is Asterisk capable forwarding D-Channel and making Asterisk box
totally transparent? If yes which version? If branch 1.2 is capable
how should I setup it right?

Thanks.

bye,
a

Thanks Philipp. Bad news.

We need recording calls with using nice functions like time synchro
and tarification.

Where should I look for solution? Is there any software only solution?
On hardware side might EyeSDN device (or similar) do the trick?

Maybe a Patton Smartnode or similar would do the trick :

ISDN ---- SmartNode ---- PBX
                  |
              Asterisk

I would be very curious to hear opinions from others on this.
Regards

artifex,
if you want call recording transparently, check out orecX.com   they 
have a commercial and an open source SIP call recording package...   no 
zap recording but if you are forwarding to sip exensions, you should be 
golden!   saw them at VON 2007 boston...  they have a recorded calls 
database lookup and web interface too...  very interesting...
