asterisk users - Apr 2008 - Global call limit

Hi,
i'm new in asterisk programming.

Maybe my question was posted thousand times but i found nothing using google.

I'm looking for a method to limit the total simultaneous calls
(inbound and outbound) that pass from internal phones to 2 SIP
providers.

I found the calllimit option but it works only on a per-channel basis.
Instead i want limit the total amount of calls, abstracting from which
SIP provider us used.

This to keep good audio quality for active calls and rejecting new
arriving: this is needed for a PBX connectect with a poor ADSL having
only 256kbit in upload: so i want permit only 3 calls (256 / 80 kbit)
and rejecting the 4th.

Any solutions?

Thanks.

if (${GROUP_COUNT(x at a)})  function in combination with Set(GROUP(a)=x)
or Set(OUTBOUND_GROUP=a at x)
