Problem SENDING Faxes to 866, 877, or 800 numbers

Why is it that Trustfax can send to some faxes and not others? In particiular, when I try to SEND a fax from Trustfax to an 866 fax number, the status remains at qued and the number of attempts maxs out. I am using a compatable file format. The error message is the receiving side does NOT answer; however when I send the same fax from a traditional fax machine, the fax goes through without an issue. Please advise.

clicking of the Max Attempts link will open a windows to explain the reason for the fax reaching it’s maximum attempts and not going through.
Trustfax allows calls to a toll-free number.
The toll-free number that you are faxing to may be restricted by the owner. the number may be setup to only accepts calls from certain area codes.
Contact trustfax at support@trustfax.com and they can troubleshoot the issue and determine if the toll-free that you are sending to is restricting incoming calls.
