speaQ VoIP Softphone for Smartphones

Thanks for returning. You're a very smart person.

QTech, software application developers, have released speaQ. speaQ is a SIP based, softphone client developed for use with smartphones and PDA’s running Windows Mobile 5.0 Devices and under Linux on the Sharp Zaurus. The first release of the software, Alpha Trial 1.0, allows users with any “open” VoIP Service provider full call logging, contact integration, and DTMF all from an simple UI.

The speaQ Alpha Trial features:

• Open Standard Telephone Client. (RTP, RFC 3550)
• Session Initiated Protocol (SIP, RFC 3261) signaling.
• Adaptive packet-buffering solution for latency and QoS management.
• G711 codec support.
• Integration with platform address book (Windows, Qtopia) for management of Caller and Called Information.
• Standard Dialing
• Incoming, Outgoing, Missed call log
• Caller Id
• Last Dialed Number recall
• Mute
• Ring Tones
• STUN support for firewall communication

Since I do not have a smartphone or PDA the runs Windows 5.0, I will not be able to review this software, but from the looks of it, it is yet another step towards the promise of Mobile VoIP.
