SIP Registrations Settings
Fax Voip T.38 Modem supports Multiple SIP Registrations. You can operate with different SIP servers simultaneously, and (or) to register multiple SIP accounts on the same server. Multiple SIP Registrations feature allows you to receive incoming calls from different SIP networks. To make outgoing calls using different SIP Registrations, should make the appropriate settings in the Outgoing VOIP Call Routing. Fax Voip T.38 Modem supports SIP registration via UDP, via TCP and via TLS. The maximum supported number of SIP registrations is not limited.
