Minimum amount of credit?

Hi,

When adding credit for international pages (or once free local pages have been used up) is there a minimum amount? If so, what is it?

Pls. respond asap.

Thanks.

The can setup the account to purchase $5 - $25 fax page credit. $5 is the minimum.
The unused fax page credit will roll-over to the next billing cycle.
Using fax page credit for additional fax pages will deduct 10 cents for each pages.
International faxing will deduct the per page rate for that country. US and Canada are not considered international.
