both of your extensions are 1000.
so in the internal context change one of them to be 1001

this problem continue for along time
i am writing, accidently i do a mistake
due to copy paste

now there is no problem about extension 1001 definition
it is correct.

note; i used x-lite but now i change my softphone with bria

and my user status;
