We prefer to receive changes to the call list by writing. Please locate your system or account number and your password or personal identification code and include it in an e-mail along with the changes you wish to make. If you are adding people to the call list it is a good idea to include a home, business and/or cellular telephone number. Please also indicate where they should be in the call order – first, second, last, etc. Please be sure that each person on your call list knows what to do in the event they receive a call from us.
