Masking in call manager


I have 3 Cisco phones with individual extension, I now need to configure these there numbers masking should be one.

Direct numbers: 03 0001 0001

                            03 0001 0002

                            03 0001 0003

How can these numbers be masked behind with 1300 123 456 so that when users dial out, people outside will see only this 1300 123 456, not the actual extension.

Can someone help me how to configure in Call Manager 9?

There is many ways you can do

There is many ways you can do this,

The easiest for you as I do not have the full setup of your cluster would be on the route pattern like below

Other options are Route Group, Gateway with calling party transformation or on the VG itself with a translation rule but depends on your setup as to what works best for you.

There is a number mask field

There is a number mask field in the DN configuration. That is what I use. But you also have to make sure you check the option "Use Calling Party's External Phone Number Mask" in the Gateway configuration.
