Sean, do you know anyone who has successfully used either to place a call? I think the weak spot is when the tower overloads nobody can dial anything, including the bypass..

Don't cell companies already provide over-ride codes to various federal agencies to obtain emergency priority access to cell service?
That would be the Nationwide Wireless Priority Service. Authorized users can dial *272<destination> to get priority on supported wireless networks. If the landline networks are also backed up, they can make the call to (710) NCS-GETS which is the gateway number for the Government Emergency Telecommunications System which provides the same priority on POTS lines. http://en.wikipedia.org/wiki/Nationwide_Wireless_Priority_Service http://en.wikipedia.org/wiki/Government_Emergency_Telecommunications_Ser vice --- Sean Harlow sean@seanharlow.info
