Zfone for Mac now available

Last month I blogged about Zfone. The Mac version is now out for public beta. A Windows version is expected for mid-April. Some aspects remind me of the PGPfone product of the last decade but updated to support the now common SIP protocol used by VOIP applications. However, unlike PGPfone, Zfone is not a standalone client but rather middleware that runs along side, and adds encryption capabilities, to a user’s already existing SIP softphone client.

In a related story, the VOIP and Gadgets Blog reports that Counterpath is set to release version 1.5 of its EyeBeam VOIP and video conferencing client – and one of the features is support for Secure Real-time Transport Protocol (SRTP) streams to secure the voice and video connections. While it is still extremely difficult to find a VOIP service provider that supports SRTP encryption, hopefully making the capability available to a wide group of potential users will generate demand and lead to the wider availability of more secure VOIP services.
