Questions, answered

Phone Extensions FAQs

Does every employee need a public phone number?

No. Extensions can identify users inside the business phone system, while public numbers and call flows can route eligible external calls to them.

Can an extension be reassigned?

Yes. An administrator can update extension ownership as staffing changes, subject to permissions and account rules.

Is Phone Extensions available on every TalkChief account?

Extension length, dialing behavior, endpoint support, and duplicate-number rules depend on account configuration.
