If you’re looking for a multi-line phone system that can handle multiple calls across many devices, you will be glad to know that you can use up to three different phones on the same Vonage Business extension (e.g., desk phone at work, desk phone at home, softphone on your smartphone or laptop). Use the same phone number, voicemail box, and extension for all your registered phones at no additional cost.


A multi-line phone system is necessary these days, whether you’re on the road and using your smartphone to make business calls, or trying to close business deals from your laptop in a hotel room, or even giving up time at the beach house to check your messages. Multiples Devices on One Extension allows you to truly work from anywhere.

  • No more lugging your phone around with you.
  • No more plugging and unplugging the phone you’re not using.
  • No more doing business with your cell phone when you’re out of the office.

Just register a softphone or second office location with the same Vonage extension.


“This is amazing. Thank you!” – Matthew Lang, PowerProit.

“I’ve been hoping for this! The reason I wanted this is I have an office in the U.S., plus two in Italy, and up to now had always carried around my phone.” – John Anderson, Ashlar LC. www.odradek-records.com

“This is a cool new feature which allows you to make business calls from your cell phone or home phone but it can go through Vonage so it appears like it is coming from the business line.” – Lou Castillo, Investor Riches. www.investorriches.com

The Flexibility of an IP Phone System

Vonage’s hosted phones systems allow businesses to communicate much more efficiently than with traditional phone systems. IP telephony allows businesses to extend their phone system’s reach far beyond the walls of their brick and mortar location. IP Phones work by registering their unique IP addresses with the system each time they are plugged in. As long as a phone is connected to the Internet, it can be located by the phone system, and thus receive calls at the appropriate extension number. Now, with Multiple Devices on One Extension, each extension can register up to three different IP addresses to connect a call.
