CHICAGO, Mar 10, 2005 (BUSINESS WIRE) -- Members of the MobileIGNITE alliance: BridgePort Networks, Commoca, PCTEL and VeriSign's mobile operator partners, First Cellular and IMC, will showcase MobileVoIP Live! at CTIA Wireless 2005. CTIA Wireless is the next stop for MobileVoIP Live!, a showcase that demonstrates voice roaming between mobile (GSM and CDMA) and Wi-Fi networks, following its debut at 3GSM World Congress 2005 in Cannes, France in February.

MobileVoIP Live! showcases the ability of standards-based multi-vendor interoperable MobileVoIP solutions to work across live mobile and Wi-Fi networks. Using various examples of services and devices, the showcase provides service providers with a real life experience for applying Internet economics to mobile services. Visitors to CTIA Wireless 2005 can experience seamless roaming of calls using a single mobile phone number identity over both live mobile and Wi-Fi broadband networks. For example, as attendees enter an area where the Wi-Fi signal offers a clearer connection, a multi-mode phone automatically connects using low cost VoIP technology to send and receive calls.

Visitors to MobileIGNITE participating member booths can test MobileVoIP Live! on a Windows Mobile-based GSM and Wi-Fi Smartphone, with a unified cellular and Session Initiation Protocol (SIP)-based VoIP user interface to make and receive phone calls.

Calls will be made on live mobile networks through roaming relationships provided through VeriSign (with International Mobile Communications for the GSM network and First Cellular of Southern Illinois for the CDMA network), combined with a wireless LAN network based on Airespace WLAN infrastructure.

The showcase is the result of the work of a number of BridgePort Networks' partners in its MobileIGNITE alliance program for MobileVoIP interoperability. MobileIGNITE brings together MobileVoIP convergence leaders to test highly integrated end-to-end solutions for service providers based on current SS7, SIP and 802.11 open standards with a planned migration to the IP Multimedia System (IMS) network environment. MobileVoIP Live! will operate at multiple locations in and around CTIA Wireless 2005 from March 14 - 16, 2005.

"MobileVoIP Live! shows the power of open standards and industry collaboration on interoperability", said Mike Mulica, president and CEO, BridgePort Networks. "Since the debut at 3GSM, we have added CDMA in addition to GSM to the live showcase and are also featuring mobile services delivered not only to combination cellular-Wi-Fi terminals but also to fixed VoIP terminals."

"The MobileVoIP solution developed by the MobileIGNITE alliance helps bridge the wireless and wired world together," said Andy Haon, director of platform product management and planning for the Mobile and Embedded Devices Division at Microsoft Corp. "We are excited the solution leverages the consistent, integrated experience offered by the Windows Mobile platform."

The MobileVoIP Live! services showcased at CTIA use a mobile operators' phone number and leverage their core network infrastructure, including the Home Location Register (HLR) of that operator. Mobile operators and their mobile virtual network operator (MVNO) partners can extend their existing services by combining this core network with the low cost technologies of standards-based VoIP such as media gateways, full IP backhaul, software based call control on low cost industry-standard computing platforms and unlicensed Wi-Fi spectrum. This allows them to compete in a cost-effective manner with other service providers that are taking advantage of VoIP's low cost structure.

"MobileVoIP Live! demonstrates the ease in which service providers can develop IP Convergence services that work across a variety of access methods" said Tom Kershaw, Vice President of VoIP, VeriSign Communications Services. "VeriSign and our global network of roaming partners can help facilitate the rapid development of hosted MobileVoIP converged services. Such services help to optimize investment and accelerate time-to-market for service providers."

"We are enthusiastic as the momentum for MobileVoIP continues to build", said Marty Singer, PCTEL's Chairman and CEO. "PCTEL's Roaming Client-VE enables secure seamless roaming across both mobile and Wi-Fi networks and MobileVoIP is a natural use and extension of this capability."

"First in France and now in New Orleans - voice roaming from GSM to Wi-Fi is truly an opportunity for global roamers to take their number with them on virtually any network and take advantage of VoIP's lower cost structure", said Ken Stewart, vice president business development of International Mobile Communications.

"MobileVoIP Convergence involves not just mobile terminals, but also enhanced business and residential VoIP clients, as people prefer to use the best device for a given task." said Jose Melendez, president and CEO of Commoca. "User experience portability from mobile to fixed broadband will be an important tool in reaching several large end-user market segments in both enterprise and consumer settings."
