Set the phone up in its own context where that is the only number they can dial.

In sip.conf for the peer.
[2065]
context=only2066
…

Then in extensions.conf

[only2066]
exten => 2066,1,Dial(SIP/2066)
exten => i,1,Playback(pbx-invalid)

[2065]
context=only2066

can 2065 be part of two context…if so what would be the correct format

context=only2066;only2000

or no

thanks
again

You can include contexts within another. May want to look in the Asterisk book to see more examples of how this works so you have a better understanding.
