Disaster plan implementation for a unified communications network

A method for rerouting communication in a unified communications network, the method comprising:

• receiving, at a first disaster plan server, a mapping of an original telephony number to a substitute telephony number;
• storing, at the first disaster plan server, the mapping between the original telephony number and the substitute telephony number as part of a first disaster plan;
• receiving, at a second disaster plan server, a mapping of an original telephony number to a substitute telephony number;
• storing, at the second disaster plan server, the mapping between the original telephony number and the substitute telephony number as part of a second disaster plan;
• receiving, at one of said first disaster plan server and said second disaster plan, a request to activate one of said first disaster plan and said second disaster plan;
• transmitting, from one of said first disaster plan server to a first routing server and said second disaster plan server to a second routing server, a message to activate one of said first disaster plan and said second disaster plan based on receiving the request to activate one of said first disaster plan and the second disaster plan;
• revising, at one of said first routing server and said second routing server, routing details to the original telephony number based on one of said first disaster plan and said second disaster plan;
• and
• routing, at a first session border controller or a second session border controller, a call to the original telephony number to a new destination based on the revised routing details associated with one of said first disaster plan and said second disaster plan.
