Voice over IP (VoIP) Application Note

HP iPAQ 500 series Voice Messenger

The goal of this document is to clearly and concisely state what HP iPAQ 500 series
Voice Messenger is and is not capable of supporting for mobile IP telephony, aka VoIP,
or Voice over IP. All the capabilities and interoperability scenarios haven’t been tested at
this point, and until then this document will be a work-in-progress. As new information
becomes available, it will be added to this document.
