Abstract: The embodiments presented herein provide an automated process for provisioning a user in a communication system. A session manager, which can be a server in the communication system that provides call connection and routing, may receive registration request from communication device (e.g. a cellular telephone, an IP-enabled phone, etc.). The session manager may determine one or more characteristics about the communication device and/or determine a load on one or more other session managers in a cluster of session managers. Based on both the communication device characteristics and/or the loads on the two or more session managers, the session manager can determine a set of session managers, which may include a primary session manager and a secondary session manager, which can manage the user data for the communication device. This session manager set information may then be sent to the communication device and to other session managers in the cluster.

Abstract: The system generates a change in the SIP INVITE message during a call transfer. Here, a user relation element involved in the call can change the header information in the message to include the endpoint view of the transferring party. Thus, the INVITE message is redirected to the transferring party's user relation element, which can interpret the received message and “unravel” the B2BUAs in the existing call path. The system includes changes in the user relation element to effect the message change and interpret the message once received. Changes to the user relation element forgo the need to change the communication endpoints.

Abstract: The present disclosure describes methods and systems for managing resources, for example in connection with call admission control or other communications or transactions in a system. In particular, a plurality of resource pools are established. At least a first or priority resource is associated with a minimum resource amount, while at least a second or normal resource pool is associated with a maximum resource amount. From the system resource pools, allocations are made to each of a plurality of system servers. If a server receives a request for priority resources that cannot be satisfied from the allocation of priority resources made to that server, that server may borrow from an allocation of normal resources. Resources can also be shared between servers. Accordingly, if required resources are not available from an allocation made to a server receiving the request for resources, that server can request resources from another server.

Abstract: A distributed call control system is provided that can allot bandwidth amongst several call controllers. The distributed call control system includes one or more access elements that interface with a cloud that execute two or more instances of call processing servers that administer call control. The cloud members negotiate and determine bandwidth allocation amongst the members and the access elements. If an access element requires more bandwidth, the access element assesses its own needs and requests more bandwidth from the cloud. The negotiation and requests for bandwidth are accomplished with a set of dynamic and static bandwidth data that regiment the control of the bandwidth.

Abstract: In one embodiment, a communication device includes an outgoing call alerting agent 196 that (i) detects that a communication device has entered an off-hook state and that a first line appearance has been selected by a user for an outgoing call, (ii) forwards a first call setup message to a third party call controller, the call setup message including a request to reserve the first line appearance for the outgoing call, and (iii) thereafter collects a set of digits dialed by the user for the outgoing call and provides the collected set of digits to the third party call controller.
