Hi Senad
i looking for same thing, that is consider absolutetimeout as a
timer, everytime is near t zero, 3 secs for example, renew it,
reacalculate real credit, and start again until some of the parties
hangup.
The problem is how to iterate in asterisk config, or in deadagi,
you will need some time values from asterisk anyway, CDR{billsec} and
CDR{duration}, because i think we have to give this control to
asterisk, he really knows the timing of calls. Now the problem number
two. Asterisk set those values above, when the call is completely
finished, i have tried with deadagi in php whit sleep function,
nothing, the values of the varialbles are set after hangup extension,
after deadagi final execution.
If I understood well, when each call is made u give him duration time
based on the billing.
Its wrong direction at start. The only possible solution is in the
asterisk. You need global variable with total time for all channels,
then you need the timer.
Timer can be one by each channel, and each channel timer decrements same
global time variable when it becomes a zero or less terminate all active
channels for that account.
The other way would be to have one timer who decrements global time
variable based on number of active channels. Timer is inactive when
there is no active channels for account.
To explain this, if timer decrement cycle is n second then he should
decrement global remained time variable ACCOUNT_TIME = ACCOUNT_TIME- (n
active channels at the moment) x (timer cycle in seconds).
Then check condition ACCOUNT_TIME = 0 if true hangup all active
channels for that account.
Then check condition (n active channels for account == 0) if true stop
the timer.
The n active channels should be checked on asterisk.
If you create account time variable when first channel of account
becomes active like AV_{some id} and timer who will process this
remaining time.
Then on each new channel for that account you just increment other
variable NAC_{some id} or decrement.
The best is that this variables be asterisk variables (global).
We have not tried above, so be my guest if you have free time :)

How about AstRTB ? Asterisk Real Time Billing --- Thameem Ansari [EMAIL PROTECTED] wrote: Hello All, I had the same question when I was writing my own billing software in java. Here is what I am doing to track multiple calls at a time from the prepaid account. 1. Keep on db table for balance and reserver_balance. 2.

Otherwise the allowed seconds is more than the allowed seconds, set absolute time out for the reserved seconds and make the call. 8. Reserved secs is a custom constant seconds, say you can reserve fund for 3 minutes (180 seconds). if the account has balance for only 2 minutes (120 seconds) then the absolute time out will be 120 seconds. 9. Once the channel status changed to reserved, insert an record to reserve_balance table with uniqueid, accountcode, amount, reserved_secs information. The above steps will handle one call so far now...and lets see how the dial plan should be, 10. In your dial plan, add an AbsoluteTimeout extension T and call another AGI script which will just to reset the absolute timeout. 11. When the particular timeout is reached asterisk will transfer the call to 'T extension which will in turn call another agi. 12. The agi will receive all the information about the channel including uniqueid, repeat the steps 2- 7 (except dial) and reset the abstimeout and this process will repeat until the channel hangup. 13. Once the channel hangup, you can either use Manager to receive the cdr event or you can set h extension (not reliable and not recommended) to calculate the real balance and update the balance table. Once you update the balance table, remove the record from reserve_balance table for the uniqueid, channel and accountcode. (these three are enough to find out the entry in that table). Now lets take the scenario for second call when the first call was active, 14. When the second call comes in, start from step 2. In step 2, we are doing finalBalance = Balance - Sum(reserve_balance) for that account code. If there is already a call on this accountcode, then this table will have one entry and the reserved amount. Get the finalBalance by subtracting the amounts. Follow step 3 and allow or deny the caller. The above said solution is very stable and doesn't overflow the memory or session and not using any threads. The only restriction here is, if we have the scenario, Call -1 balance = $0.10 destination= 1 (which is US) rate = $0.02 per minute reserveSecs = 10 minutes (600secs) finalBalance = $0.10 - $0 (consider this is first call and no entry in reserve_balance table) = $0.10 allowedMints = $0.10/$0.02 = 5 minutes = 300 seconds. AbsoluteTimeout = 300 seconds (this is less than the default reserveSecs so set this as abstimeout) Call -2 balance = $0.10 destination= 1 (which is US) rate = $0.02 per minute reserveSecs = 10 minutes (600secs) finalBalance = $0.10 - $0.10 (consider this is second call and already an entry in reserve_balance table) = $0.0 allowedMints = 0 seconds. announce the denied ivr.

There's an application (sorry, which one, escapes me at the moment), that gets around this by reserving a certain amount of credit per call. Say the amount is 10 minutes, if you have 30 minutes worth of credit, you can have 3 concurrent calls good for 10 minutes each. The way I understand it, if you only have 15 minutes left in your account, the first call will last for 10 and the next concurrent one for 5 minutes. -- JP Carballo http://www.netfone2x.com Bringing the world closer.

The solution that I looking for is to take a average-time-call, and
create a timer with it.
Then base on this value, and the price for destination call, every
time the average-time-call pass substract the consume credit from the
real credit, and set absolute timeout, for this average-time-call.
But I dont know how to implement this is asterisk. With pseudo-code

RE: [Asterisk-Users] billing realtime
You keep eluding to the answer yourself. Asterisk Manager is the way to go. Check out http://search.cpan.org/~xantus/POE-Component-Client-Asterisk-Manager/. Relatively simple event based method for using Asterisk manager. What I would do is register a handler to track new calls, and calls ending. Every time you get a new call, add it to a hash with the customer_id as the key. Seperately register a callback that keeps re-calling itself at X second intervals. It would cycle through the hash of active calls decrementing remaining time for each, and then kick anyone with 1 second remaining. I have a single script running 12 instances of POE::Component::Client::Asterisk::Manager (1 for each of 12 servers) under a single POE kernel to track 2500 channels (comings and goings of MeetMe users) and it's had no problem keeping up. Just make sure that you avoid any long running loops as POE is not multi-threaded. For something like this, I think you'll find 1 instance of a single script much easier to track and debug than a whole bunch of instance of an AGI script.
