Internal Calling

Internal calling is free with your Telzio service. Telzio enables you to call internally by directly dialing an extension. You can call or transfer calls to a User, Group, or Call Flow by their extension. Calls to other extensions are included as part of your service, which means internal calling does not count towards your plan usage.

Using the Telzio app or an IP phone, simply dial the 3 or 4 digit extension of the User, Group, or Call Flow you want to reach.
