[Asterisk-Users] working on calling card for *

[d hinton]

hi
below is an outline, if you will, of the features/apps i'm planning on adding to asterisk. they will allow for pre-paid & calling card calls via an asterisk enabled system. if i'm correct, these can be added via common perl scripts doing mysql calls placing variables into the config files. now because i'm new to asterisk, i need to learn how asterisk works with scripts and also before i get started i need comments and suggestion about the process of the call, how the call will be handled by asterisk. also if any if this stuff is already set please let me know. ALL HELP WILL BE APPRECIATED!

well here's what i got:

Process of a Pre-Paid or Calling Card call;  Calls will arrive over multiple local t1's that are plugged into a zaptel based pci cards. the calls are then authenticated, compressed with the required compression (if needed) then routed either via the ethernet WAN port(VoIP) or via Long Distance T1's which are also connected to zaptel based pci cards. below is the process of a call;

Caller is prompted to select a preferred lang.
