asterisk users - May 2006 - Dropping Number on Dial Out

I have been having a strange issue with my Asterisk 1.2.1 server.  I have a
TDM400 for the three POTS lines I have and I can receive calls without any
problems.  But sometimes (not everytime, but 70%) when I dial out of those lines
it drops a number and of course gives me the telco error message.  How do I know
that it's dropping?  Because I thought it was a line problem and the tech
came out and found nothing wrong and we could dial out with a phone and have no
problem.  I asked the tech to trap the line while we dialed out from Asterisk
and he found that on the 10 digit dialing that sometimes only 8 or 9 digits were
being passed to the telco switch.

One catch to all of this, I have one of the three lines is a Vonage line - this
works everytime and I suppose because the Vonage PAP2 box queues the number
before it dials (according to it's dialplan).

I'm not sure where to even look for the answer on this one.  I have looked
in the configs and nothing APPEARS wrong but who knows?

I would appreciate any help, this is really annoying!

Thanks,
Craig

Asterisk is probably starting to dial too fast. Add a "w" in your dial
statement, this will make it wait half a second before dialing, giving
the time for the dialtone to appear. You can add multiple "w" to have
it wait longer

On the asterisk CLI, type "show application dial"
