Abstract
A distributed VoIP system includes a network and a first switch at a first site coupled to the network. The first switch is configured to provide telephony services to a first communication device. The system also includes a second switch at a second site coupled to the network. The second switch is configured to provide telephony services to a second communication device. The system also includes a spare switch coupled to the network. The spare switch is configured to provide telephony services to the first communication device if the first communication device is unable to register with the first switch, and the spare switch is configured to provide telephony services to the second communication device if the second communication device is unable to register with the second switch.
