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:

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).
