Thomson's Cirpack VoIP switches allows operators to offer global telephony solutions to business users. Thomson’s Cirpack IP Centrex solution incorporates all the features of hosted PBX solutions to be used on corded phones in the office together with mobility features, without forcing users to change their mobile handsets.

A bundled package will offer subscribers more competitive and easier to use services with unique features such as single number for both the IP Phone and GSM phone for inbound calls, unique caller ID for outbound calls, dual ringing on incoming calls to choose to use the fixed or mobile phone to answer, automatic routing of inbound calls to the proper terminal in the proper location, seamlessly placing and receiving calls over WiFi anywhere on the Internet using the usual geographic phone number, maintaining calls over GSM when loosing WiFi signal, etc.

Mobility gives the user the freedom to benefit from IP Centrex services from any location: in the office, on the move or even at home. With Thomson’s Cirpack Mobile IP Centrex solution, users enjoy new PBX features on their legacy GSM device, such as short dialing, transferring calls or activating a multiparty conference from the GSM phone, being filtered and monitored by an assistant, as well as integrating the GSM phone in a hunt group for instance.

Because Thomson’s Cirpack telephony switch supports all the specific GSM signaling protocols and mechanisms, it can connect the VoIP and GSM service logics together to provide a full fixed/mobile convergence solution using existing GSM phones. Operators can offer convergence features with no major changes in their networks or in the mobile devices. Any legacy GSM phone can be used and will benefit from these features because the convergence is managed within the network.
