Voice Mobility’s UCN Vmerge is now integrated with the Google Apps solution suite to provide workplace and campus customers full collaboration functionality. The Google Apps suite includes Gmail, Google Talk, Google Calendar, Google Docs, Contacts, Mobile apps and other collaboration tools all using the workplace or campus domain. UCN Vmerge adds unified communications to complete messaging, collaboration, calendaring and presence functionality.

Enterprise clients want the ability to enable their enterprise voice and fax communications to work seamlessly with Gmail. UCN Vmerge allows full on-premise or hosted enterprise PBX integration with a hosted personalized Gmail service. Industry analysts have calculated that the average IT manager spends 75% of their budget on infrastructure maintenance, leaving a small amount for new technology. With Google Apps, free or premium service combined with the cost-effective UCN Vmerge solutions, IT managers can roll out new technology to keep pace with consumer technology.

“By integrating UCN Vmerge with Google Apps, workplace and campus customers have price-effective options for collaboration functionality,” said Mike Seeley, Voice Mobility’s VP of Global Sales. “This is like deploying a full Microsoft® Exchange® server, Active Directory® and Office Communication Server® at a fraction of the cost. No longer are customers forced to utilize expensive on-premise solutions from providers like Microsoft for collaboration functionality."

"The market has asked for this type of solution and Voice Mobility is proud to be the first to bring it to the market. This new functionality will bring the same change to the workplace and campus markets that Salesforce.com® brought to the CRM market. Combine this functionality with our mobile applications and we can deliver unified communications on all Symbian™, Windows Mobile® or Blackberry® devices.”

UCN Vmerge enables users to access voice, fax and email messages directly from their Gmail account and synchronize all messages across all their devices — in essence, gluing the Google Apps to the enterprise telephony infrastructure. For example, if an email is heard via the user’s mobile device, it will be show as ‘read’ in their Gmail account. Other functionality enables users to:
· Send faxes directly from their Gmail account;
· Receive voice and fax messages in their Gmail account;
· Record and deposit office conversations in their Gmail account;
· Manage live calls from their desktop;
· Click-to-dial internal and external numbers from any Google application;
· Synchronize call logs;
· Import Google Contacts into UCN Vmerge for remote access;
· Utilization of least cost routing available from the enterprise PBX;
As is standard with all Voice Mobility’s UCN solutions, included are message waiting indication and message notifications, mobile workforce integration and offline access to the user’s inbox. Our next UCN Vmerge release will offer PBX presence integration with Google Talk and other exciting features.

The combined collaboration suite is easy to set up and manage: Google Apps is installed in six easy steps, and UCN Vmerge is compatible with the majority of PBX and Centrex solutions in the market.

In most cases, one day is all it takes for a certified Voice Mobility technician to install the UCN Vmerge product with flexible training and support options available. Workplace or campus customers also have the choice between purchasing the UCN Vmerge solution outright or selecting managed or hosted solutions from Voice Mobility and its certified partners.

OTTAWA– May 25, 2006 – Bell Canada, Nortel and NewHeights Software today announced the market availability of the Bell Canada Personal Communication Manager (PCM) solution. The Bell Canada PCM is a PC-based soft-client that brings together voice, messaging and multimedia communications into a unified interface that can be used in the office or while working remotely.
The PC-based solution enables government and enterprise workers to communicate and collaborate with greater ease, flexibility and efficiency, whether between colleagues, work groups or with external customers and publics. Laptop users are able to undock their laptop and carry with them the same telephone and messaging services and profile that they enjoy at their corporate desktop. The Bell Canada PCM also enables users to initiate calls and multiparty conferences with point-and-click ease, know the telephony and messaging status of their colleagues with real-time presence and availability information, and access over 250-features that simplify communication processes — all through a single, intuitive interface on their PC.

“Knowledge workers need to effectively communicate from work, home or on the road to meet their business objectives,” said Paul Rowe, Vice President of Enterprise Marketing, Bell Canada Canada. “With the Bell Canada PCM, our customers can provide their employees with cost effective mobility and productivity gains. Bell Canada is pleased to partner with dynamic companies like Nortel and NewHeights to harness the power of IP to provide feature-rich communications from any broadband connection worldwide.”

The Bell Canada PCM directly addresses three core needs of today’s enterprise. First, to leverage telephony presence and remote call / answer services to reduce costs associated with cellular network usage, second lines for home offices, calling cards and traditional toll charges. Second, to enable mobile knowledge workers to remain accessible to their customers and colleagues while making it easier to manage activities such as: multiparty conferencing, call handling and caller-associated information retrieval. Third, to bring added value to existing network investments, enabling the introduction of new telephony features without replacing existing infrastructure investments or service contracts.

The Bell Canada PCM solution is the result of extensive interoperability between Nortel’s SIP-based Multimedia Communication Server (MCS) and NewHeights Desktop Assistant soft-client technology. The Bell Canada PCM can be used both with the on-premise and off-premise versions of the MCS, the 5100 MCS and 5200 MCS respectively. Additionally, the Bell Canada PCM operates in conjunction with Nortel’s IP and TDM sets.

“Integrating Nortel’s Multimedia Communication Server with NewHeights soft-client technology has enabled Bell Canada to bring-to-market the world’s most advanced, secure and reliable enterprise soft-client solution,” said Owen Matthews, Chief Executive Officer, NewHeights. “We are entering a new era of vendor collaboration leading to new ways of communicating and doing business. The Bell Canada PCM is a clear example of the innovation possible when companies like NewHeights and Nortel team up to enable new services to the enterprise and government.”

“Nortel’s MCS is a prime component to our IP Multimedia Subsystem (IMS) strategy and the Bell Canada PCM solution is a real-world example of how we are leveraging Session Initiation Protocol (SIP) to drive new and feature-rich services to the enterprise,” said Alan Stoddard, General Manager, Carrier Multimedia Solutions, Nortel. “Bell Canada has chosen an innovative solution with Nortel and NewHeights, both for enabling telecom services and ensuring an end user experience that is enjoyable, intuitive and tailored to the business communication processes of today's enterprise worker.”

Nortel has extensive expertise deploying its SIP-based Multimedia Communication Server with more than 40 SIP-based multimedia customers globally. In addition, Nortel has more than 300 carrier VoIP networks installed around the world.

The Bell Canada PCM integrates NewHeights SIP-based flagship soft-client, the Desktop Assistant 90 (DA-90) and the Nortel Multimedia Communication Server to offer:

• Point-and-click management of calling features, handling and routing
• Initiation of voice, e-mail and instant messaging with one or two clicks
• Drag-and-Drop multiparty conferencing
• Integration with Microsoft MSN Messenger, Microsoft Office, Microsoft Live Communications Server, and other enterprise applications and platforms

Citel Releases EXTender IP6000, Enabling Gradual VoIP Migration Path for Distributed Enterprises

SEATTLE – April 25, 2006 – Citel, The VoIP Migration Company™, today announced general availability of the EXTender IP6000, enabling enterprises with multiple locations to take a cost-effective, phased approach to IP telephony migration with minimal business disruption.

Rather than supporting multiple PBX systems and remote connections, Citel’s EXTender products allow enterprises to connect remote call centers, home workers, and branch offices to a central digital PBX over an IP network, significantly reducing telecom operating costs and simultaneously improving business operations by providing single voice mail and call center applications, central reception, and four digit dialing throughout the enterprise.

As the business case evolves and the enterprise is ready to complete the migration to SIP, the EXTender IP6000 can be software upgraded to accommodate a premise or service provider hosted IP PBX, leveraging the existing handset and wiring infrastructure at each location.  This phased migration path allows enterprises to immediately realize the advantages of a central PBX platform, then complete the full migration to SIP telephony in the future, without having to “rip and replace” existing infrastructure.

Hundreds of blue chip clients already rely on Citel’s robust EXTender product line to seamlessly distribute the features and applications of a central digital PBX to remote call centers, home workers, and branch offices.  The EXTender IP6000 expands this product line with a new lower price point and an assured upgrade path to SIP-based hosted or premise IP telephony in the future.

“Although the market for new telephony infrastructure is shifting rapidly toward IP, many enterprises with existing PBX infrastructure require a more solid business case for immediate migration to VoIP,” said Mike Robinson, CEO of Citel. “The EXTender IP6000 addresses this reality across a multitude of PBX platforms.  This solution provides an immediately cost-effective and productivity enhancing business case as the first step, followed by a simple, flexible path to complete the migration to IP telephony in the future.”

Citel’s EXTender IP6000 is available in a 12-Port configuration, which can be scaled to accommodate the number of stations at each remote site.  The EXTender IP6000 is compatible with many leading PBX platforms, including Avaya/Lucent Definity and Magix, Nortel Meridian and Norstar, Alcatel, Ericsson, Iwatsu, Toshiba, and Panasonic.

About Citel.
Citel is the VoIP Migration Company™. Citel enables SMBs, large enterprises and service providers to realize the cost and productivity benefits of IP telephony while at the same time leveraging their existing PBX infrastructure. Businesses with single or distributed locations and PBX vendors can now deploy next-generation IP applications and services at their own pace, with little business disruption. Service providers can deploy hosted IP telephony services quickly, without having to “rip and replace” existing enterprise PBX handsets. With the acquisition of MCK Communications in January 2005, Citel has the most robust VoIP migration product line on the market today. Citel is a privately held company with corporate headquarters in Seattle, and development offices in Calgary, Alberta (Canada) and Nottingham, England (UK).
