I do not know about the specifics, but it seems to me that you would need an AGI that would track the usage and compare that before placing a call. To switch I do not know how you tell the sim adapter which one to use, but surely there must be a command somewhere, the mere fact that agi allows you to script something like this fairly easily means that it shouldnt be a big problem, assuming you code :) And you can even pick your favourite language given how the AGI talks to asterisk even 'unsupported' languages can be used. -- Trixter http://www.0xdecafbad.com Bret McDanel UK +44 870 340 4605 Germany +49 801 777 555 3402 US +1 360 207 0479 or +1 516 687 5200 FreeWorldDialup: 635378
