Asterisk with prepaid card

[sami-hep]

i am trying to create something like a prepaid card number.
where i can create prepaid cards and assign credits to it, then this credit must be reduced after each minute of a call.

so i should be able to create cards, assign credits, credits get reduced every minute.
this should only work for a specific trunk.

is it easier for me to customize a SQL report from the CDR and use it ?

or should I install some billing software? is freeRadius a good example? a2billing?

so what do u propose guys? first or second choice? what are the pros and cons of each choice?

[sami-hep]

any help would be appreciated.

If you cant code and doesn’t know the Asterisk dial plan logic use a2billing, if not you can use the L option of the dial command and MYSQL to complete this project.

So just to make it clear, a2billing is a software that allows me to do what i need and it supports pjsip channel?

And yes i think i can code.
I believe i need to create sql database, it has to be a real time database. Then start an event where if could count minutes and so on which then i can reduce the credits while call is still going? Something like that i guess

count the time real time is harder, better set the time limit before dialing using the L option and the destination number and the amount of minutes for that particular customer

Ohhh thanks.
So i think it s a doable thing after all.
I need to set L option(which i still not familiar with)
Which sets for me time limit.
And this will trigger a flag(m assuming), where then i have the right to hang up the call!

Quick sample

[inbound]
exten=>200,1,set(LIMIT_WARNING_FILE=beep)
same=>n,Set(LIMIT_PLAYAUDIO_CALLER=yes)
same=>n,Set(LIMIT_PLAYAUDIO_CALLEE=yes)
same=>n,Set(LIMIT_TIMEOUT_FILE=demo-thanks)
same=>n,Dial(Local/200@mymusic,L(60000:30000:10000))

[mymusic]
exten=>200,1,Answer()
same=>n,MusicOnHold(default)

Limit call to 60 seconds, play a beep every 10 seconds, and at the end play the asterisk-demo thanks message to caller and calleed

[sami-hep]

I will try it next week and let u know what happens.

Thanks again
