How do I change the number that shows on outgoing calls?

There are 2 ways to set this up on the MN3300.

For  BRI/ISDN2e lines only follow these steps:

1. Log in to your Mitel system. If you don't know how to do this please see How do I connect to my MN3300 system?

2. Go to User & Devices, Telephone Directory Management and then the Associated Directory Numbers form.

3. Click Add and make your changes.
   Note: 200 refers to the telephone directory number of your extension etc.

4. The associated number is the one which will be presented to the called party when you dial out i.e.

   Directory Number - 200
   Associated type -  CPN Sub
   Associated Number -  0113 234 5678

Or for  BRI/ISDN2e & PRI/ISDN30 lines follow these steps:

1. Log in to your Mitel system. If you don't know how to do this please see How do I connect to my MN3300 system?

2. Go to Trunks, Digital,  ISDN and then Outgoing Call Characteristics.

3. Select the DID Range for CPN form.

4. Highlight an Index number, click Change.

5. Make your entries on the form i.e.

   Index - 1
   DID Range - 200 - 210 or 210
   CPN Substitution (Number to show) -  0113 234 5XXX or 345XXX

   Again as in the example above, 200-210 refers to your extn number range you wish to set.

6. Go to Trunks, Digital, ISDN and then Outgoing Call Characteristics.

7. Select the CPN Substitution form.

8. When the DID Ranges window loads click Add Member.

9. Add the index number you have set up above to the ISDN trunks you wish to use.

10. Now give it a test, if it doesn't work, reduce the number of digits entered in the CPN Substitution, i.e. 345XXX to 45XXX

11. If reducing the number of digits doesn't work, make sure you have the DDI assigned to the main trunk number.
