asterisk users - Aug 2007 - Load testing/burn-in for Sangoma quad PRI card

Hello all -

I'm about to deploy an asterisk server here at work.  Before
deploying, I'd like to do an extended load test on the system.  I
currently have T1 crossover cables connecting ports 1->2 and 3->4.
Would there be an easy way to script generating a bunch of calls
across these spans?  I envision generating 23 calls over the 1->2 span
and 23 over the 3->4 span.  I'd like to start the calls and then let
them stay connected for several days to make sure things are in order.
 This number of calls would be a *lot* higher load than this system
would ever see, but I just want to be safe.

Is there currently any script out there that would facilitate this
sort of testing?

Here's my current config:

linux-2.6.21
asterisk-1.4.10
zaptel-1.4.4
wanpipe-3.1.3
libpri-1.4.1

Thanks!
-Erik

Having calls connected for that duration is worthless testing... What  
you need to do is call setup and tear down many times per second... I  
recommend trying to accomplish 20-30cps at 1ms to 10ms variable  
durations.  That will expose any bugs quickly.

And that my friend is how you expose any bugs... leaving calls up for  
days is easy... its the setup and tear down that you'll have bugs in.

Brian - thanks for the reply.  If you read my email, I believe I make
it fairly clear what my needs are.  I have a 4-port Sangoma PRI card
installed.  Crossover cables are connected between ports 1->2 and
ports 3->4.  I'd like to generate a bunch of calls over those spans.
