I have 4 PSTN lines connected to TDM410. I can make exact 60 minutes of free calls from each of 4 pstn lines... Can I configure Asterisk to call thru pstn line that has free minutes? For example

Outgoing calls are going through PSTN 1 for 60 minutes. When I use all of these free minutes - outgoing calls go thru PSTN 2. When I use all free minutes from PSTN 2 outgoing calls go via PSTN3. 

You will need to keep track of the call duration for each channel in a persistent store -- something like MySQL.

You may also want to read up on setting the absolute timeout on a channel so a caller won't consume all of your 'prepaid' (nothing is free) minutes and drive you into unexpected charges.
