Extension Dialing

Now you can call anyone in your company and they’re only three or four digits away, even if they are in different locations.

Don’t you just love the convenience of extension dialing? 8x8 extensions typically use the 4-digit model, but we also offer 3-digit or 5-digit extension dialing. And don’t worry. Everyone gets their own direct phone number too. So you have the best of both worlds.

Extension Dialing at Its Best

Extension dialing gives you so many ways to save time and be more efficient.

  • Call other employees—Just pick up the phone and dial those few digits, whether you are calling someone at the next desk or across the country.
  • Transfer calls faster—Use the transfer function and dial the extension number to connect callers to the right person. You can either transfer the call directly, or tell the person receiving the transfer what it’s about before you transfer the call.
  • Act like one location—Even if everyone works in different locations (out of their homes, different stores, or even in different countries) with extension dialing you are only an extension away from each other. Your callers don’t need to know who is where.

Your Extension is Mobile

Here’s another cool thing. Your extension can go with you as you are traveling, working at home, or on vacation. We give you so many ways to stay connected and available.

  • Bring your IP phone—You can take your IP phone with you anywhere. All you need is an Internet connection. Working out of the downtown office or at home today? Bring your phone too and never miss a beat.
  • Call Forwarding—Easily forward all calls to your extension to your cell phone, home phone, any phone you choose. Want them to all ring at once? No problem. Want them to hunt you down in a specific order? You can do that too!
  • Take It Online—Login to Virtual Office Online, our web-based dashboard or our Virtual Office Desktop client and you can make and take calls right from your computer. You can even set it up to work in tandem any nearby phone that you want to designate as your temporary office phone.
  • Use It to your iPhone, iPad or Android—Download the Virtual Office Mobile app to your iPhone, iPad or Android device so you can make and take calls from your smartphone or tablet, just like it’s your 8x8 extension.
