Restrictions for VVX phone

BillC65 · ‎04-11-2025

I have a VVX 450 that needs to be restricted to call only a handful of configured phone numbers. The phone should also not be able to dial internal extensions. How can I configure this on the phone?

Hello @BillC65 ,

Welcome to the HP community.

Unfortunately, your post does not contain the currently used Software version for the HP Poly product or what type of SIP server is being used.

This is important, especially in the future, when someone finds this post in days, months, or years.

Please do not simply edit the original post but reply with the versions.

In the FAQ or the Read 1st section, we remind users why this is important. The FAQ also contains easy information how to identify these questions and help.

The easiest way to do this is via the SIP server the device is registered to.

If no other volunteers reply, I suggest you contact our Support organization in your region. Details are in my Signature.

Best regards

Steffen Baier
