VoIP and SIP phones for Android seem to be all the rage at the moment with 3CX having recently released their free client.
Now Infrax Systems has also jumped on the boat. The corporation provides unified products and services for the Utility and Energy industries and has now announced the release of an Android-based mobile phone with various data applications. The phone system is encrypted and works on the HTC Desire handset which allows users to safely manage data and voice calls.
It operates via a peer-to-peer connection to provide secure VoIP. The calls can be made on HSDPA (3.5G), Wi-Fi, EDGE (2.5G) and UMTS(3G)networks. There are Industrial, Government and Business phones available, with a Utilities model to be released soon.
