ok this can be done trhoguh COR list

lets say the port is 0/0/1

do the following

dial-peer cor custom

name fxo

name all

dial-peer cor list restrected

member fxo

dial-peer cor list not-restrected

member fxo

member all

dial-peer cor list fxo-only

member fxo

dial-peer cor list all-ports

member all

creat dialpeer going through that fxo

for example

dial-peer voice 9 pots

destination-pattren .T

Cor outgoing fxo-only

port 0/0/1

now lets say u have other ports u want other employees to use it

dial-peer voice 9 pots

destination-pattren .T

Cor outgoing all-ports

port 0/0/2

now apply the cor list in the incoming directionto the extention line

for example:

Ephone-dn 1

cor incoming restrected

Ephone-dn 2

cor incoming not-restrected

based on the config above the DN 1 will have access only to port 0/0/1 while DN 2 will have access to both !

if u want only DN have access to only that port just remove the member fxo from not-restrected

so the DN 1 will have access to port 0/0/1 and DN 2 will have access to port 0/0/2

good luck
