Abstract: A telecommunication system that can selectively establish communications with one of a plurality of telephony devices associated with a particular telephone number for a device in an enterprise network. More particularly, the system is configured to route an incoming telephone call received from an external device, such as a mobile device for example, to one or more of a plurality of telephony devices associated with the telephone number. The plurality of telephony devices may include personal digital assistants and other remote devices. In one embodiment, the system comprises a network server configured to connect the incoming telephone call from an external device to a telephony device, where voice communications are encrypted for transmission by the network server to the external device from which the incoming telephone call is received, and encrypted voice communications received from the external device can be decrypted, re-encrypted and/or stored by the network server if required.

Abstract: A telecommunication system and method that allow a data exchange to be initiated while a user is engaged in a voice communication using a non-class A endpoint (e.g., cellular telephone, personal digital assistant, etc.) with another party. One example method maintains a first voice communication leg to the wireless device and a second voice communication leg to the second device, inputs a request for the data exchange during the voice communication, disconnects the first voice communication leg, parks the second voice communication leg and waits for data to be transmitted to or from the wireless device. Once it is determined that the data exchange is complete, the method establishes a third voice communication leg to the wireless device, unparks the second voice communication leg and connects the second and third voice communication legs.
