Setup same extension on multiple lines on Cisco Phone

Hi,
I am trying to setup Cisco 7965 work as follows:
-Line 1 gets registered to extension 1000
-Caller A calls 1000, it shows up on line 1
-Caller B calls 1000 at the same time, it shows up on line 2

-Caller F calls 1000 at the same time, it shows up on line 6

Can it only be one in SEP$mac.cnf.xml file? If so, what is the exact syntax? If there is another better option than SEP$mac.cnf.xml file, please let me know.

Thank you.

I suppose if your Cicsco phone is configured with multiple registrations named for each ‘line’ you could do it this way with a Caller ID match

IE

1000.1 'Line 1’
1000.2 ‘Line 2’

1000.6 ‘Line 6’

exten => 1000,1,Dial(SIP/1000.1)
exten => 1000/B,1,Dial(SIP/1000.2)
exten => 1000/F,1,Dial(SIP/1000.6)

This is assuming User B has the caller ID of B and user F has the caller ID of F.
