[Asterisk-Users] same extension on multiple sip phones?

[Kevin Hanson]

I have a need to have the two sip phones register with the same 
extension (at least I think I have the need :)

A client wants an incoming call to ring at the receptionists desk and 
also at their desk.  If the receptionist is in it will be answered there 
and put on hold followed by a "Joe, you have a call on line 1".

Is there a way to do this w/ asterisk?  I've played with two phones with 
same sip registration and it seems the last one to register is the one 
asterisk recognizes.

Thanks,
Kevin
