Improve Fax Transmission Reliability for Toll-Free to Toll-Free Numbers
Currently, when both sender and recipient use toll-free numbers, faxes are routed through a generic path since toll-free numbers lack fixed geographic endpoints. This routing is less reliable and often results in failures. We request an improvement in how TFN to TFN fax traffic is handled, with more robust routing, better support for explicitly setting the “sent from” toll-free fax number, and clearer error feedback when failures occur.
