Feature Codes

Super AdminTenant AdminEnd User

Feature codes are star codes you dial from an extension to use a feature by phone, such as checking voicemail. The Feature Codes page in the portal is a read-only list of the codes defined for your domain.

Common Feature Codes

Code What It Does
*99 + mailbox number Check voicemail, e.g. *991001
*99 AI Voice Agent (when it’s installed)
A code that’s listed in the portal isn’t guaranteed to be active. The two codes in the table above are the ones that work. For Do Not Disturb and call forwarding, use PBX › My Extension instead.

Using Feature Codes

Dial the feature code from any registered SIP extension or desk phone. You’ll hear a confirmation tone or announcement when the action completes. Voicemail (*99 plus your mailbox number) walks you through further prompts.

Tell your end users how to check voicemail by phone. It saves support calls.
