New release of Windows Mobile softphone – support for g729 codec and VoIP tunnel
A new version of Vippie for windows mobile  has been released today.  The softphone supports  g729 codec which provides very efficient compression saving the bandwidth usage and yet offering high voice quality. Combined with our new tunnel where in addition an RTP payload can be adjusted it gives excellent results even with  weak internet connection (for example over GPRS).
