Abstract: Extending dual-mode phones using SMS messages. When operating in cellular mode, SMS messages originated by a mobility controller in the enterprise command features such as indicators on the dual-mode phone. SMS messages are received by an agent in the dual-mode phone. A mobility controller connected to the enterprise SIP PBX and voicemail system receives messages for example indicating voicemail status and sends specially formatted SMS messages to the cellular phone to operate indicators. Similarly, the dual-mode phone issues SMS messages to the enterprise mobility controller to request the enterprise PBX perform features such as call conferencing, call pickup, and call pull.

Abstract: Improved handling of RTP streams in digital networks. A switching device in a digital network such as a controller, bridge, or access point examines streams flowing through the device. The device monitors the initial UDP packets of a stream until a predetermined number of packets have been monitored. The device monitors and fingerprints the header portion of UDP packets, looking for RTP header bit patterns, ignoring certain RTP packet types, and caching others. This fingerprinting process attempts to match cached packet header information against subsequent packets in the stream to detect RTP streams. If the stream is determined to be an RTP stream, then the RTP type from the packet header is used to tag the stream. In one embodiment, such tags are QoS tags. Tagging may also be based on the control session port used.

Abstract: Indicator control for dual-mode phones. While under control of an enterprise Wi-Fi network, indicators on a dual-mode phone can be controlled using SIP messages. When operating in cellular mode, indicators on the dual-mode phone are controlled by SMS messages which are intercepted on arrival. A software agent connected to the enterprise SIP PBX and voicemail system receives messages for example indicating voicemail status which cause the software agent to send specially formatted SMS messages to the cellular phone and operate indicators.
