This invention includes a system and method to enable a device to determine the presence information of another device over a secure communication network. First, the device and a presence server establish a secure connection. Next, while the initial secure connection with the presence server is established, the device generates a randomly created token and provides it to the presence server. The token is used as a shared-secret by the device and the presence server to secure future presence communications over a non-secure connection. Next, without the need to again enter a password or establish a secure connection with the presence server, the device uses the shared-secret to sign, encrypt and convey presence information to the presence server over an arbitrary connection. Finally, the presence server may share the first device's presence information with another device.

A method for establishing communication via a VoIP network bypasses the IP PBX component conventionally used to obtain address information. Instead of obtaining the IP address from a location register of the IP PBX, the method involves use of a server configured to assign and provide to the caller's communication device a unique address (IP address/port) of a proxy. The caller then sends a Short Message Service (SMS) text message to the callee with the assigned address of the proxy. Thereafter, the caller and the callee connect at the assigned address of the proxy, thereby forming a communication path. Preferably, the devices operated by the parties are conventional smart phones. According to the preferred embodiment of the present invention, the method further comprises the steps of: determining whether to encrypt the communication; and encrypting the communication, if it is determined that the communication is to be encrypted. Preferably, the Station-to-Station (STS) protocol is used to encrypt the data packets.

Technique for bypassing an IP PBX

A mobile telephone () with a camera feature () that functions as a motion detection device. The mobile telephone can include an image capture software routine () and a motion detection software routine (). The image capture software routine can use the camera feature to automatically generate one or more time spaced images. The motion detection software routine can detect motion based upon differences between the time spaced images. The motion detection software routine can selectively utilize a multiple algorithms.
