IsoFax adds SIP support

Enterprise fax without fax hardware

IsoFax 12.2 adds support for inbound and outbound Fax over IP using the Dialogic Brooktrout SR-140 T.38 stack.

Existing IsoFax customers can migrate from legacy PSTN fax hardware to IP—PBXs and SBCs from from Cisco, Avaya, and others, or connect directly to T.38 capable SIP trunks from Verizon, CenturyLink, Sprint, and other telecom providers.

T.38 allows private, error-free faxing to and from an IsoFax server and PSTN gateway, or end-to-end for T.38 capable endpoints.

Costs savings over direct PSTN connections can be dramatic.
