asterisk users - Jul 2004 - Question when using a Cisco as a PSTN GW

HI all

I have a little question, and since there is a  alot of Cisco Gurus
somebody might be able to help me.

I think It is an easy problem.

My PSTN proviver strips the first digit in the callerid on all incoming
calls.

So when the call reaches my Asterisk I am missing a "0" in the CLID

I guess it should be easy to prepend a digit on all incoming calls on a
Cisco 5350 ?  

But I am unsure how a translationrule for that would look like.

Anybody ?

/Regards Mike
