asterisk users - Apr 2007 - Passive E1 Pri Tap for Voice Recording

Dear All,

Is it possible to install * in front of a Avaya IP 406 system via a T
connector E1 tap so it's external to the Avaya system?

We would like to record upto 60 channels (2 * ISDN30e). This may increase
later.

Also, could the calls go into the cdr for retrieval/browsing later?

What hardware/server would you recommend?

Thanks.

Gavin,

Call Endance and ask them about their "Lawful Call Intercept"
solution(s)
using their DAG TDM E1 cards on Linux (Endance.com).  

Cheers.

I did this with a Nortel MICS a few years ago. No problem.

The dialplan was something like:

[incoming]
exten => _X.,1,setvar(filename) ;We did something with callerid and call
date and time, but I can't really remember
exten => _X.,2,Monitor(filename)
exten => _X.,3,Dial(Zap/G2/${EXTEN})

[outgoing]
exten => _X.,1,setvar(filename) ;  If you want to record outgoing calls
exten => _X.,2,Monitor(filename); use these two lines, otherwise, just skip
them
exten => _X.,3,Dial(Zap/G1/${EXTEN})

Obviously, this isn't production code, but you should get the idea. If
you're in a 2-party area, you probably need to make your employees sign a
disclosure, and play a sound file to your callers to warn them that the call
is/may be recorded. While it will waste space, I recommend starting the
recording before the file is played. That way, if you're ever challenged,
you'd have something to back up your position that the caller knew. Add the
signed disclosure, and you may be OK.

Of course, I am no lawyer. And you probably ought to talk to one before you
do this. We did, and he had some helpful pointers on what to include in the
disclosure.

There are some areas that will require you to play an annoying beep to
callers. We didn't have to do that, so I'm not sure of the best way to
go
about it.

Good luck,
David
