What Is An Internal Call? 

In telecommunications, an internal call refers to a call placed between two extensions within the same company. By contrast, an external call is a call placed with a number outside of the organization. In the past, internal calls required dialing an extension. Companies that use VoIP software can place internal calls without extensions. In a contact center, internal calls are sometimes called agent-to-agent calls.  

 

How to Make Internal Calls 

There are different ways to place internal calls: 

  • Dial the required extension determined by your company phone guide 

  • If using VoIP, you can simply call the person you want to connect with 

  • If you are unsure, ask your Helpdesk
