[asterisk-users] Limit total length of calls to a specifig SIP peer

[Laurent CARON]

Hi,

I'm currently using a cheap SIP provider for outbound calls.

I do have 6 channels to them.

In their terms of service there is the following limit:

The total duration of calls during one single day should not exceed 24 
hours or we do have the right to terminate the contract...blah blah

What is the best way to use this provider as long as we are below let's 
say 22h in a single day ?

Thanks

Laurent
