It might be wise to disassociate the term "extension" from a device... 
because in Asterisk an extension is a set of instructions that execute a 
set of applications. For your need you should probably have multiple 
devices in sip.conf, and have the extension dial all of them.

ie:

Dial(SIP/145_1&SIP/145_2&SIP/145_3)

3 phones would each be registered on the machine as 145_1, 145_2, and 145_3.

The first one to pick up would get the call and all the rest would stop 
ringing.
