Session Manager anti-looping creates a model that is an effective barrier to looping, efficiently identifying a loop condition by maintaining temporary individual call counters for header sets within temporal parameters and terminating the loop condition upon detection. The system provides an administrator with adjustable parameters for loop detection count and loop detection interval, thereby allowing protection against loop conditions, both inadvertent and intentional.

A communication system, method, and components are described. Specifically, a communication system that supports dynamic device pairing of communication devices is described. Such pairing is accomplished using a feature or pairing server, without requiring modification to associated communication endpoints. Moreover, sequenced applications can be applied for all communication endpoints when pairing is in effect.

Method and apparatus for dynamic device pairing

A hot-desking application and methods of operating the same are described. The hot-desking application can be provisioned as an explicit sequenced application for all user addresses of record in addition to being provisioned as an implicit sequenced application for all of the possible hot-desk endpoint addresses. Through such provisioning, the hot-desking application can, among other things, allow for calls to be placed directly from a hot-desk endpoint but still show the user's address of record as the calling identity.

System and method for enabling hot-desking

A communication system, method, and components are described. Specifically, a communication method is disclosed which enables a media device and control device to be dynamically paired to one another and a control link call to be established between the media device and the control device. The control link call can be utilized to permit the media device to be controlled by the control device while the media device exchanges media with a communication device operated by another user.

Dynamic device pairing with control session establishment

A proxy server causes an authentication authority to authenticate a client in response to a first Session Initiation Protocol (SIP) request of the client on a connection. It does not cause the client to be authenticated in response subsequent requests on the connection as long as the underlying connection is not broken, the subsequent requests are on behalf of the same client, the client has not been removed from the system, the client's password has not changed, a 'safety net' timer has not expired, or any other policy that the server chooses to enforce. This eliminates the overhead of constant re-authentication in response to each SIP request.
