Enhance the Customer Call Experience with Phone Number Extension Features

Add services like unlimited extensions, dial by extension, and speed dial to quickly connect callers.

What is a Phone Extension?

An extension is a three to six-digit number identifying a specific call path configuration that allows you to dial and connect to another caller internally. This is not a DID phone number but rather an internal extension. Outside callers can directly reach you by dialing your organization's main phone number followed by the intended party's extension.

The phone number extension is one of many convenient features offered as part of our VoIP service platform for small businesses and enterprises. Phone extensions can be used in a number of ways in your business to support your call center or contact center objectives for excellent customer experiences.

Our phone number extension features let you have unlimited extensions for your business telephone number and company phone system. You have the option of choosing extensions, including the number of digits in the extensions. Callers can also dial directly by extension or use the speed dial feature.


Advantages of Phone Number Extensions

Traditional landlines can't offer the convenience and superior experience delivered by a VoIP system and its phone number extension feature.

    Multiple connection options

    Whether it's a business landline at a call center or an iPhone or Android smartphone, you can use the phone number extension to connect your team with customers or employees.

    More accessibility

    Customers are able to reach their intended point of contact much faster than having to use a directory menu, waiting for a receptionist, or getting stuck with voicemail.

    Made for remote teams

    Even though companies use remote teams, they may not want their customers to know how their staff is deployed around the world, so the phone number extension seamlessly connects everyone through a main number and then transfers them to local numbers.

    Value-added service

    Rather than paying extra for these convenient features, phone number extensions are included in our VoIP service platform, giving you a wealth of tools to enhance customer and employee relationships.

Dial By Extension

Dial by Extension allows a caller to dial an extension directly rather than dial the full phone number or contact the receptionist. This feature lets you reach your party faster. Customers can also exit an auto-attendant by dialing their party's extension at any time.

For example, you can use this feature to dial your party's extension straight from your handset regardless of location.


Unlimited Extensions

Unlimited extensions are included in the price. This means you can have several different extensions ring the same landline or mobile phone or you can add extra extensions for conference rooms. Each extension comes with a voicemail box and Find Me/Follow Me settings. You can choose an extension to call a ring group that includes all available agents in a certain department so that the caller is sure to speak to someone rather than be sent to voicemail.

Unlimited extensions can be used in many ways. You can set up extensions for each employee even if two employees share the same desk phone. Or, you can have a general extension for different departments like Sales or Billing.


Speed Dial

Speed dial options can be set up on any phone on our system. You can configure your speed dial options for quicker calling on your desk phone or with your click-to-call desktop interface, softphone, or mobile app. Speed dial settings are unique to a specific device.

For example, speed dial is often the easiest way to quickly connect with people and extensions you dial frequently. Once you set up this feature, you can dial by one button to get connected faster.
