Method and apparatus for managing calls

摘要

A system that incorporates teachings of the present disclosure may include, for example, one or more components for receiving a call request at a first server from a first end user device, transmitting the call request from a first server to an intermediate server for establishing a voice or video call over an IP multimedia subsystem between the first end user device and a second end user device via a second server, and routing the voice or video call request from the first server to the second server using a second IP address when an undesired condition is determined to be associated with the IP multimedia subsystem. The second IP address can be obtained from a group of IP addresses stored in a memory of the first server and the group of IP addresses can be associated with other servers. Other embodiments are disclosed.

主权项

1. A first session border controller device, comprising:
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
transmitting a first IP address to a second session border controller device responsive to establishing a first call session with the second session border controller device, wherein the first IP address is stored by the second session border controller device, and wherein the second session border controller device transmits the first IP address derived from the first call session to a remote server that is accessible to a plurality of session border controller devices;receiving a call request from the second session border controller device, wherein the call request is for a second call session, wherein the call request comprises the first IP address, wherein the call request is routed from the second session border controller device according to the first IP address responsive to determining an undesired condition at a network; andestablishing the second call session with the second session border controller device.
