Extension Masking

We just switched over to a new hosted VOIP provider and i was wondering is there a way in the config file to change it so that when i dial out it shows a different extension other then mine. What i am trying to overcome is that now when i dial a user internally it displays my personal extension. I am on the IT support team and do not want them to call me back but go to our support queue. So instead i want it show our support queue extension and different name when i call internally.


Our voip provider already allows us to change our DID that we call out EXTERNALLY. The issue is just internally. Please let me know if this is possible and what needs to be done.


Also the firmware that i am on is

Re: Extension Masking

Hello alexquala,

welcome to the Polycom Community.

The routing should be handeled by the SIP server. The SIP provider could simply program your extension into a routing that cannot be called and an additional code is needed to be able to dial this.


It should not be the phones issue to display a "fake" number to the caller.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
