asterisk users - Jun 2006 - Voip* 300 minutes limit, credit expires

Betamax makes our life more and more difficulty, hehehehehehe.

I found (today) that the free calls are limited to 300 minutes per week. 
It is good to know what "excess" use means!
That gives now also a challenge in the dialplan!!!!

Let's assume we have 5 accounts, each one has 300 minutes.
We use a variable as provider and get the right value of the not 
outmaxed provider into this variable.
How can we do that?

exten => _9011Z.,103,Dial(SIP/00${EXTEN:4}@voipdiscount,30)
should be replaced with ${voipdiscount} 

and we need before a statement that finds the content of this variable.

Q: Does anybody know how to download the "recently used" statement?

I am interested how Voip* will react to the recently law change in 
Germany, where for mobile phone operator (and I assume that this law can 
be used for Voip* as well) a prepaid value may not expire anymore!!!!

Now lets look at Voip* pricing:
12 US$  per month for 300 x 4 minutes, with the expiration within 3 
months (13 weeks) ==> 1200/(13*300) = 0.3 cents in the BEST case!!! If 
you use more than 300, than you have to pay "at least" whatever that 
means in real numbers  1.2 cents.

It is getting more and more complicated, and that for pennies!!!
Unfortunately you cannot reach anybody there. I would like to have only 
ONE account and pay more for multiple use than this kind of tricks!

just some thoughts!
