Abstract
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.
