Disaster recovery : re routing your telephone system

Have your phone provider re-route incoming calls to another number you specify

This method is possible and would work in a disaster recovery situation. However you still need to think of the following points:-

• What will a phone providers response time be?
  
• Who will they re route calls to?
  

Considering the first point unless you have a special agreement or Service Level Agreement (SLA)you could be waiting longer than you would really like to. Other factors affect the effectiveness of this method such as the number of incoming calls and how many different numbers your calls come in on.

If you have standby offices then the issue of who to re route calls to is simple. If you do not you'll have to choose pre selected numbers as already specified in your Business Continuity Plan (BCP).

The issue of who to route calls to does arise in other methods of handling incoming calls in a disaster scenario but are compounded in this method if you have to rely on someone else to do it.


The more control you have over your telephone system the more tightly you can control how calls are routed and be sure of the response times.
