Is there a way to pass to another provider when the free minutes in the first are gone?

i imagine you could implement a2billing and use each account with the appropriate info.

at voxilla.com, i attempted a macro to accomplish this, never implemented it though, so i don't know if it works and no one ever commented...

------------------------

If anyone an comment that would be great. I have not had much experience writing macros, so this was a stab in the dark, maybe it will allow you to see my thoughts though.

I had thought of that, but ethics are a personal matter.

My particular account is not with the free type of company as the OP's apparently is. My VSP provides a subsidized amount of minutes of int'l calling each month, each month with the bill per account. If I didn't use it efficiently, it would be dumb. I'd be paying them twice.

I was looking to figure out a counter that told me the first line used 100 minutes and would then eat up the second lines balance.

I am still looking to keep an easily accesible counter like the ast2billing app, but haven't had time to implement it.

Regardless of the difference in ethics involved, the method should be the same. People use the same tools for different things.
