The present disclosure provides a system and method for applying authentication and security policies in a SIP environment. In accordance with one embodiment, there is provided a method for use on a SIP server, comprising: establishing a persistent connection with a user agent (UA); initiating an idle connection timeout countdown timer; performing authentication of an initial REGISTER request using a first level of authentication; and terminating the persistent connection when the initial REGISTER request is not validated before expiry of the idle connection timeout countdown timer.

System and method for applying authentication and security policies in a SIP environment

The present disclosure provides a system and method for Session Initiation Protocol (SIP) user agent identification and efficient binding. In accordance with one example embodiment, there is provided a method for use on a Session Initiation Protocol (SIP) registration server for registering user agents, comprising: receiving a REGISTER message which includes a binding key; determining whether a prior binding associated with the binding key exists in a registration repository; and creating a new binding associated with the binding key and adding the new binding to the registration repository when no prior binding associated with the binding key exists in the registration repository.

System and method for SIP user agent identification and efficient binding

An apparatus, and an associated method, for a communication device having a SIM card, or other removable storage element, that permits hot-swapping of the storage element. Notification of hot-swapping of the removable storage element is detected. Responsive to the detection, provision is made to resubscribe to push service notifications that are disabled upon removal of the removable storage element.

Apparatus, and associated method, for resubscribing communication device to a push notification service

A device and method are described for establishing a dialog between Internet Protocol (IP) end points using a peer-to-peer (P2P) architecture. The device, method and computer readable memory utilize servers to determine one or more possible addresses to attempt the dialog establish using. The device and methods described allow for an early discovery of an end point address which can be used for the dialog establishment.

Dialog establishment over a peer-to-peer architecture

A mobile device can send a notification to place a call using a PBX (e.g., using SIP signaling) or receive a notification of call availability for the mobile device at the PBX. An authentication token is provided over a data channel for use in authenticating the mobile device when calling the PBX on a voice channel. However, when the mobile device calls the PBX (e.g., on a DNIS number, where ANI information is made available to an application server), if ANI information is found to correspond to the mobile device, the PBX can send tone(s) indicating that the mobile device can respond with an abbreviated validation tone, rather than the entirety of the authentication token. If the ANI information is not obtained or not matched, then a different tone(s) is sent, indicating to provide the authentication token. If the authentication token provided does not match or if the mobile device does not respond, the voice channel is not set up.
