Description:my dial plan:

exten => 1380,1,SetVar(LIMIT_CONNECT_FILE=timeleft)
exten => 1380,2,SetVar(LIMIT_TIMEOUT_FILE=timeleft)
exten => 1380,3,dial(iax2/dm:d@123.123.143.122/playback||HgL(20000:10000))
exten => 1380,4,hangup

Here is console output:

As you see everytime as I dial something call limit timer reset to initial value.

i'd think this is expected behaviour, i wouldnt want it any other way.
The dial limit is an option to make a prepay application easier, its not meant to be a complete app_prepay.

(If i'm missing something, please correct me.)

As I understand S() and L() options allow to control the maximum duration of the call.
If I say: dial(iax2/user@host/ext||S(20) the call duration can't be more then 20 second. 20 - may be the value returned by billing system depending from money user has on his account and we can't allow him to talk more.

L() gives more control with possibility to notify user about his limit but it should behave in the same way as S() for limiting call.

So the statement dial(iax2/user@host/ext||L(20000:10000)) should not allow user to make more then 20 seconds call. Or I'm missing something?

Right now when construction dial(iax2/user@host/ext||L(20000:10000)) is used I CAN prolong the call duration simply typing digits on console. And instead of 20 seconds I can talk 1 hour, 2 hours... as much as I want.
Thats a bug for sure.

ooooh, oké, i missed that.
(thought you were dialing a second time).

Its a bug, but no one should have axx to your CLI anyway, so i'd say its a minor one ?

unless of course you are using an asterisk -rx to do things...

I belive its a major bug.

Imagine you have system with

exten => _X.,1,SetVar(LIMIT_CONNECT_FILE=timeleft)
exten => _X.,2,SetVar(LIMIT_TIMEOUT_FILE=timeleft)
exten => _X.,3,dial(iax2/user@termination/${EXTEN}||HgL(${MAXCALLDURATION}:60000))
exten => _X.,4,hangup

dial plan.

I can call you and talk any time I want.

can you also reproduce this without using the CLI ?
By: Dmytro Mishchenko (arkadia) 2004-08-06 07:17:43

yes I can.

Should be fixed in CVS.  If you continue to have trouble please find me on IRC, as I'll need to login to your machine.
