Call policy enforcement and routing is based on user location. A plurality of endpoints is provided for receiving and making calls. Each of the plurality of endpoints are assigned a default policy for controlling call authorization and providing call routing rules. A mapping of policies for a plurality of locations is stored. A location of a client associated with one of the plurality of endpoints is identified. A location-based policy is obtained from the stored mapping of policies of the plurality of locations based on the identified location of the client. The obtained location-based policy is applied instead of the default policy assigned to the client associated with one of the plurality of endpoints.

Subscribers of an enhanced communication system are enabled to indicate invocation or clearing of media specific features such as music-on-hold or video-on-hold. The invocation or clearing is transmitted to participating end points as a Session Initiation Protocol (SIP) re-INVITE message with Session Description Protocol (SDP) attribute descriptions identifying the feature, applicable media channels and whether the message is for invocation or clearing of the feature.

A facility for providing extensible alert types is described. The facility includes an endpoint component that has an associated application, an alert handler component provided by the application for handling received messages and providing alerts to the application, and a message transport component that receives a message, determines whether the message contains an alert, locates an alert handler to handle the alert, and provides a portion of the received message to the alert handler component so that the alert handler component can handle the alert. The facility can receive a request to register an alert handler, add an indication of the alert handler in a mapping data structure and, upon receiving a message containing an alert, identify an alert handler to handle the alert contained in the message.

A facility is described for managing parallel requests in a communications environment having devices or applications ('request handlers') that support serial and parallel message processing. In various embodiments, the facility receives messages directed to a recipient from an application and sends a first message to the recipient without sending subsequently received messages to the recipient. Upon receiving a response from the recipient to the first message, the facility determines whether the recipient supports parallel or serial message processing. When the recipient supports parallel message processing, the facility sends the subsequently received messages to the recipient without awaiting a response to a message before sending another message. When the recipient supports serial message processing, the facility sends a subsequent message after receiving a response to a previously sent message.
