VoIP Phone Service: How It Works

Voice over Internet Protocol (VoIP) may sound complicated, but our voice service is used in the same way as traditional telephones. Just plug your regular home phone into our adapter, and voila! Phone service over the same reliable network as your Internet.

Learn More

Your voice signals are converted into data so they can be transmitted over the Internet. 

You don’t have to get a fancy new phone to use Voice. Just plug your regular landline phone into our analogue telephone adapter (ATA), and you’re ready to go.

Frequently Asked Questions

Can I use the Internet and my voice service at the same time, or is it like dial up?

Yes! You can use the Internet and your voice service at the same time. While they both use the same network, there’s plenty of capacity to handle Internet and voice calls simultaneously.

What's the difference between voice service and traditional landline phone service?

Whereas landline phone service uses a network of telephone wires dedicated to the phone service, Colorado Central Telecom Voice calls are carried over the Internet.

How reliable is Colorado Central Telecom's voice service?

The reliability of our network is our highest priority, but if you lose your Internet connection because of a power outage at your home, your Internet and voice services will not work.

You can protect against this by purchasing an inexpensive uninterruptible power supply (UPS), which provides a battery backup for your equipment. Voice service can also be affected by network outages.

What standard features come with voice service?

Colorado Central Telecom’s voice service includes unlimited local and long-distance calls to the US and Canada, and over 35+ advanced calling features, such as caller ID, call waiting, call forwarding, and voicemail. You can also keep your existing phone number or get a new local number. It’s up to you!

Can I keep my existing number if I switch to Colorado Central Telecom Voice?

Yes! When you sign up for Colorado Central Telecom Voice, just notify customer service that you’d like to port your number. You’ll have to fill out a form authorizing the transfer, but we’ll take care of the rest.

Just make sure that you keep your existing phone service active until your number has been ported to Colorado Central Telecom Voice.

Do I have to subscribe to Colorado Central Telecom Internet to get Colorado Central Telecom Voice?

No. Voice service runs over the internet, so you must have an internet connection to use it. That internet connection can be provided by Colorado Central Telecom or another provider.

Does Colorado Central Telecom's voice service support E911?

Colorado Central Telecom’s voice service does support E911, but there are some important differences to be aware of in the event of an emergency because power failures and Internet outages will affect your ability to dial 911.

  • As with all VoIP delivered phone services, Colorado Central Telecom Voice may not work during a power outage. This can be prevented by purchasing a battery backup, also called an uninterruptible backup power supply (UPS).
  • Your voice service operates over the same network as your Internet service. As such, your voice service will not function in the event of an Internet outage or other service interruption, even if the battery backup is working.
  • If you move your analogue telephone addapter (ATA) to a new location without updating your registered address with us, the Public Safety Answering Point (PSAP) may be unable to automatically identify your location when dialing 911.

More information is available at our E911 disclosure page.

How do I access my voicemail?

For Residential Users: Once the ATA has been installed, a working corded or cordless telephone may be connected. Then you can dial (star) *62 to set up and access your voicemail. You may be prompted to set up your voicemail PIN the first time you access the voicemail.

Voicemail may also be accessed, along with other phone settings (such as Call History or Call Forwarding options), in your Phone Service Web Portal from any computer. Using a web browser, go to and log in to access the options within the phone portal.
