T.38 Fax SIP Trunking

This is how Fax over IP should be. Connect a handSIP T.38 Fax SIP Trunk to your fax server, IP-PBX, VoIP gateway, or fax machine/ATA to get reliable, low-cost FoIP.

Reliable faxing over low-cost T38 Fax SIP trunks.


Reduce Fax Failures

Most T.38 FoIP providers disable Error Correction Mode (ECM). WE DON’T! And there’s a darn good reason why we don’t. ECM is arguably the most important feature of faxing. That’s why we leave it enabled on all of our handSIP Fax SIP Trunks.

Use What You Have

handSIP T.38 Fax SIP Trunking is compatible with Useit Fax Server from Imecom, and any other IP fax solution or ATA device. Enhance what you already have and experience what FoIP is supposed to be like.
