RE: VoIP - PREFIX /DIGIT STRIP

To the best of my knowledge....
Prefixes do exactly what they are, put a prefix before the digits are sent -
in dial-peer 1 on router a, the sent string would look like ,,5...... (the
commas are just one second pauses). I don't see any digit striping, I would
expect to see a translation rule or num-exp for digit striping.

I don't know of an 'consolidated' source for this info - but here are the
tech tips for voip, etc.

Subject: VoIP - PREFIX /DIGIT STRIP

Greetings:

I'm cramming on VoIP and it's associated QOS.
I have 5 different Cisco Press books open on my desktop to
go with the 3 CCO browser window.

Anyone got a consolidated, tested source that could simplify my efforts?

Also, I'm brain cramping on digit striping w/PREFIX ? I read it over and
over and look at the
config and it still MAKE SENSE, too me.
