New Palm OS VoIP Application
Articulation is a new VoIP application for the Palm OS from Hampton Software. It is compatible with most Palm OS 5+ devices with a microphone that can access the Internet via Wi-Fi/Bluetooth or EDGE/GPRS. Articulation is the first service independent VoIP phone for Palm OS, which means you can use it with a number of different VoIP service providers.
Articulation supports the standard SIP VoIP protocol. The app will work with the majority of SIP VoIP service providers and the developers have a list of confirmed compatible providers. At this time the program is not compatible with Skype.
