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. The set of session managers may then manage the user data for the communication device.

Automatic user redundancy determination

An initial request is received to establish a communication session. The initial request contains a communication address of a first communication device. A communication server detects that the communication session cannot be established across a primary network. In response, the initial request is repurposed by changing the first communication address to a second communication address. The changed request is sent to a communication system, which adds a field to the changed request that indicates that the changed request is to be sent via a secondary network. The changed request is sent with the field to the communication server. The changed request with the second communication address is sent to a gateway to establish the communication session across a secondary network. A portion of the communication session is established using the second communication address. The first communication address is sent in the portion of the communication session using Dual-Tone-Multi-Frequency (DTMF).

Communication failover in a distributed network

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.

SIP transfer in a back-to-back user agent (B2BUA) environment

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. In responding to a request to share resources, a server can attempt to fill the request as if the request had originally been made to that server.

Resource allocation using shared resource pools

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.

Efficient and cost-effective distributed call admission control

Methods, devices, and systems are provided for identifying unique points in communication processing for substituting and restoring identities associated with the communication. These specific replacements facilitate communication requests to-and-from external identities to be treated similar to communication requests to-and-from enterprise users, thereby allowing enterprise users to access enterprise-based communication preferences and services via non-enterprise devices.

Network framework associating non-enterprise phone with enterprise users

A distributed call control system is provided that can allot bandwidth amongst several call controllers. The distributed call control system includes one or more servers that execute two or more instances of call processing servers that administer call control. The call processing servers form a cluster or group. The cluster members negotiate and determine bandwidth allocation amongst the members. If a member requires more bandwidth, the call processing server, of that member, assesses its own needs and requests more bandwidth from other members. The negotiation and requests for bandwidth are accomplished with a set of dynamic and static bandwidth data that regiment the control of the bandwidth.

Efficient and cost-effective distribution call admission control

A telephone is provided with a port for disconnectably connecting an external information source, such as an MP3 player, to the telephone, and an on-hold function that operates while a call of the telephone is on hold and either presents to the telephone's user the information from the external source if the external source is connected, or presents to the user on-hold information from a telephone network if the external source is not connected, or presents silence at the user's option, irrespective of whether or not the external source is connected.

Telephone using an external media device to provide on-hold information

Methods, devices, and systems are provided for marking one or more entities of a call as internal/external such that certain call features can be invoked by servers and other devices residing behind a gateway. More specifically, entities of a call can be marked as internal/external based employing an assessment algorithm to determine whether the calling endpoint is an internal or external endpoint and/or whether a user of the calling or answering endpoint is an internal or external user. Once this determination is made, the call can be marked accordingly such that the appropriate features can be invoked.

Internal/external network identifier

Methods, devices, and systems are provided for taking a pluggable extension and applying it to a unique set of a user population to handle their preferred and user-centric alerting relationships. More particularly, the pluggable extension allows a user to have their personalized contact resolution algorithm applied by a server to calls initiated by them or directed toward. The contact resolution algorithm is pluggable to any server and does not need to be built into the server itself. Moreover, multiple users can refer to and use the same pluggable contact resolution algorithm.

Pluggable contact resolution

Methods, systems, and devices are provided that propose allocating bandwidth in a distributed network. According to a decentralized mode of operation, bandwidth between network devices is cooperatively shared and managed, allowing one or more call processing modules to selectively and intelligently place calls or perform activities. A single authoritative mode of operation for a given communication link is also provided, wherein one or more network devices may consult an authoritative member to determine if sufficient bandwidth is available to support an activity. Various triggering events or conditions may facilitate the transition from one mode to another. Audits or accountings are conducted, wherein devices may update or synchronize information stored in a control table related to system bandwidth.

Alternative bandwidth management algorithm

In one embodiment, a communication device includes an outgoing call alerting agentthat (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.

Line appearance reservation for SIP endpoints

The present invention is directed to an architecturefor setting up a communication between first and second communication devicesand, the first communication devicecorresponding to a first directing serverand first communication managerseparate from the first directing server, comprising a contact servicing agentoperable to (a) receive a call set up message at least one of addressed to and originated by the first communication device; (b) determine that the first communication devicehas a corresponding first communication manager; (c) forward the call set up message to the first communication managerand request the first communication managerto perform at least one of call originating and terminating processing; and (d) rout the call set up message to a destination referenced in the call set up message.

Originator based directing and origination call processing features for external devices

The present invention is directed to a telecommunications systemfor routing a contact to a selected address, comprising (a) an input for receiving a contact message comprising a source address and a destination address of a subscriber communication deviceassociated with a subscriber and (b) mobility agentfor determining whether or not the source address in the contact message corresponds to a proxy serverand, when the source address corresponds to a proxy server, causing the contact not to be routed to a selected address and, when the source address does not correspond to a proxy server, causing the contact to be routed to the selected address.
