Connecting VoIP with Public Phone Networks : DigInfo

Mobile Technika and International System Research jointly released their FMC Enabler package, a support tool for IP phone solution.
The package offers fixed and mobile FMC (fixed mobile convergence) communication on a Windows Mobile smart phone.
With the implementation of this package, users can use both types of phones as an IP phone and as a mobile depending on the situation.
The PPPhone FMC Enabler package includes a soft phone or PPPhone for mobile IP telephony which meets the IETF (Internet Engineering Task Force) standards, SIP standards, and a VoIP server which connects data networks with PSTN (which are Public Switched Telephone Network) ones.
