CME External Phone number mask

[louisbohls]

Is it possible to configure a distinct external phone number mask per extension on CME?  My outbound connections are FXO lines.

Thanks

you can but the number you need to use it over the PSTN through your FXO has to be allocated to you by the teleco

i am not sure with FXO you have range of numbers DID or its just one number per line !

can you put more details about the numbering plan you looking for ?

for example if you have two FXO lines are you looking to send calls from certain ip phones through one line and others through the other line !!

The concept of "external number mask" is not applicable with FXO.

When calling, you can only choose to show the number assigned to the line, or anonymous. Nothing else is possible.

in this case i think the best way is to enforce some ip phnes to use one FXO while the others use the other FXO and so on:

voice translation-rule 1
rule 1 /^9/ /19/
!
voice translation-rule 2
rule 1 /^9/ /29/
!
voice translation-profile FXO1
translate called 1
!
voice translation-profile FXO2
translate called 2
!
dial-peer voice 9 pots
destination-pattern 19T
port 0/0/0
!
dial-peer voice 91 pots
destination-pattern 29T
port 0/0/1
!

apply the translation profiles created above  to each Phone DN you want it to follow the rules above For example :
Extension 1000 dials 9 for an outside dial ton, the translation profile FXO1 will change the called number by that DN to be pre pended with 19 which matches dial-peer voice 9, and the call will use port 0/0/0. same concept will be applied on DN 1001

ephone-dn 1 dual-line
number 1000
translation-profile incoming FXO1


ephone-dn 2 dual-line
number 1001
translation-profile incoming FXO2


if you want to restrict the  calling number from being seen when certain phoes uses one of the lines, for example using the above example if you want iphone with number 1000 and all other phones using the same dial-peer (9) to have thier calling number to be show as unknown:

dial-peer voice 9 pots

clid restrict

good luck
