Voip.ms Notes

The voip.ms Virtual Fax service does not provide real-time incoming faxes for FaxTalk purposes. This is a store and forward fax service. Faxes that are sent to your Virtual Fax DID are answered by voip.ms fax servers and then are forwarded to FaxTalk using the T.38 fax protocol. They will also appear as a received fax in your voip.ms web panel. Outgoing faxes are always sent in real-time and are also logged in your voip.ms web panel.

Faxes sent and received using a Voice DID are sent and received in real-time. FaxTalk must be actively monitoring incoming calls to receive faxes.
