A method is provided in one example embodiment and includes communicating initial digits associated with an original request for a call and receiving a message indicating an incomplete address for the original request. The method also includes responding to the message by appending additional digits to the original request to generate a new request. The additional digits are buffered before receiving the message indicating the incomplete address associated with the original request. In other embodiments, the original request is a session initiation protocol (SIP) INVITE message that includes a uniform resource identifier (URI), which reflects an address for reaching a destination user. The initial digits can be partially matched against a dial plan in order to trigger the message associated with the original request. The additional digits are configured to satisfy the message and to connect the call. The message associated with the original request can be a session initiation protocol (SIP) 484 message.

A technique for managing sessions in a communication network that does not subscribe to registration events immediately after an entity in the network is registered but rather delays subscribing to these events until a time that such notification would be normally used, such as after a revocable session has been established with the entity. An entity registers to enable sessions to be established with other entities in the communication network. After a session is established, a check is performed to determine if a subscription to be notified of events that warrants revoking the session already exists. If not, a subscription is established to be notified of events that warrant revoking the session. If during the session a notification is received indicating that an event that warrants revoking the session has occurred, the session is revoked.
