As part of the Fixed Mobile Convergence (FMC) solution offering, damaka's Voice Call Continuity (VCC) technology provides a seamless user experience across different access networks using a single access device. With growing number of dual mode phones (supporting GSM/CDMA and WiFi), the demand for a consistent user experience is getting stronger.

Leveraging this technology offering, a user on a single access deivce (mobile phone) could seamlessly switch his/her voice session between a circuit switched radio network and packet switched raido network (such as WiFi, WiMAX, LTE) or vice versa. In doing so, damaka's VCC solution would ensure the continuity of the call session by maintaining the appropriate state with a central server (for example an IP Multimedia Subsystem - IMS).

damaka VCC client on the mobile device would monitor for user defined WiFi/3G/4G signal strength to maintain the call on the packet switch network. As the signal strength deteriorates below the threshold value preset by the user, the VCC client would automatically switch the active call session to a circuit switch radio network. On the flip side, if the user is on a circuit switched network and enters a WiFi/4G network zone, the VCC client would seamlessly handoff (HO) the session to the packet network. In doing so, this technology helps the user to reduce the cost of the call by switching to a lower cost VoIP call.
