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.

Voice over IP in Wireless Heterogeneous Networks
Voice over IP in Wireless Heterogeneous Networks: Signaling, Mobility and Security (Signals and Communication Technology)
The requirements for good quality VoIP communications are difficult to achieve in a time-varying environment due to channel errors and traffic congestion and across different systems. The provision of VoIP in wireless heterogeneous networks requires a set of time-efficient control mechanisms to support a VoIP session with acceptable quality. The focus of Voice over IP in Wireless Heterogeneous Networks is on mechanisms that affect the VoIP user satisfaction while not explicitly involved in the media session. This relates to the extra delays introduced by the security and the signaling protocols used to set up an authorized VoIP session and to the disruption caused by the user mobility during the session. Voice over IP in Wireless Heterogeneous Networks thus investigates and proposes cross-layer techniques for realizing time-efficient control mechanisms for VoIP: signaling, mobility and security.
