asterisk users - Feb 2005 - limit SIP extention outgoing calls

Hi
how do i set an SIP users to make outgoing calls that is worth only $5. if they
exceed $5 they can't make any calls. what i need is not a calling card, but 
to limit outgoing calls for SIP users depedning on a value i give.

I use realtime asterisk.

Thank You

Translate it to a time value, whatever you charge per minute or $5.00 is
worth,  
Use "L" option in Dail string, example:
exten =>
_9NXXXXXX,4,Dial(SIP/${EXTEN:1}@pstn-spa3k,60,trL(600000:240000:180000))
