What is how to call an extension?

Here's information on how to call an extension:

Calling an extension typically involves dialing a specific number or sequence of numbers that correspond to the desired extension. The precise method can vary based on the type of phone system in use, whether it's a traditional Private Branch Exchange (PBX), a Voice over Internet Protocol (VoIP) system, or a mobile phone network.

• Internal Calls (Within the same system): Dialing an extension internally usually just involves dialing the specific digits assigned to that extension. For example, to reach extension "123", you would simply dial "123". Read more about internal calls.

• External Calls (From outside the system): Reaching an extension from an outside phone number often requires calling the main phone number of the organization and then entering the extension number when prompted. Some systems may use an auto-attendant that answers the phone and provides options or allows you to dial an extension directly. For this method check external calls.

• Direct Inward Dialing (DID): Some extensions have their own dedicated phone numbers, called DID numbers. This enables callers to reach a specific extension directly without going through a main number or auto-attendant. Find more direct inward dialing information.

• VoIP Systems: VoIP systems often offer features like softphones (phone software on a computer), mobile apps, or IP phones. Using these, calling an extension is often as simple as selecting it from a directory or dialing the extension number using the softphone's interface. To learn VoIP Systems read here.

Important Considerations:

• Dialing Codes: Some phone systems may require a dialing code (e.g., "9" for an outside line) before dialing an external number or an extension.

• Auto-Attendants: Many systems use auto-attendants to route calls. Listen carefully to the prompts and follow the instructions to dial the desired extension.

• Operator Assistance: If you're unsure of the extension number or how to reach someone, you can often dial "0" to reach an operator or receptionist who can assist you. Understand more of operator assistance.

• Mobile Phones: Calling extensions using mobile phones is often done via an app associated with the VoIP or PBX system used by the organization. In other cases, you might need to dial the main number and then enter the extension. Learn about Mobile Phones.
