asterisk users - Sep 2009 - E1/T1 Tapping call recording in Asterisk - Testing needed

Howdy,
I've spent a couple of days writing a new feature for Asterisk that allows
to record calls in T1 or E1 PRI lines using Asterisk connected to tapped
lines. This means that you don't have to install anything in the
PBX's/telco
equipment that is going to be monitored, all you need is to install a device
like the PN 633 Tap Connection Adapter that is available for example, from
Sangoma, however I am sure there must be other vendors out there offering
similar devices. Then you need to pull a pair of cables out of the adapter
to your monitoring system with Sangoma boards configured in high impedance
mode (I don't know if Digium or other vendors boards expose
that functionality to users, but you may want to test and find out if
works). More detailed instructions can be found at Sangoma's site or my
blog:

http://www.moythreads.com/wordpress/2009/09/26/sangoma-tapping-solution-for-asterisk/

The patches are already out there in the bug tracker along with some SVN
branches.

https://issues.asterisk.org/view.php?id=15970
https://issues.asterisk.org/view.php?id=15971

I'd love to get feedback in the bug tracker in order to get this feature
into Asterisk soon :-)

Also don't hesitate in asking for help with the configuration.

Moises,

You forgot to add that in order to monitor one T1 or E1 circuit you
need two ports on your card...
So that might be getting expensive with Sangoma cards.... You can do
the same with cheap Tormenta
cards that sell for ~$350 (I did that some time ago)

Anyways all zaptel/dahdi cards can be set to high impedance since all
the framers support it...
However I'm pretty much sure it's not part of the drivers as of now.

I had to enable the high impedance mode in the tormenta driver for
myself for tests...

Is your code vendor locked to Sangoma ???

Hello Martin, not at all. The code is intended to be part of chan_dahdi
Asterisk channel driver and as such any card capable of using the dahdi
interface can benefit from it.
