little tough, ld 18 set up disa with a good password so he can use rcfw to change his remote dest from the road.. another possible way it to allow him to use his mb with the zero out option for callers..
we use it here, this is john, to leave a msg and page me just wait for the tone, to call my cell press 1, and i change the cell number to my home number when i am on call.. not that bad, i did setup disa but perfer the zero out
