Multiple Devices on One Extension overview
With this multi-line phone system, you can use up to three different phones on the same Vonage Business Communications extension (e.g., deskphone at work, deskphone at home, and softphone on your smartphone or laptop). This 3-line phone system lets you use the same phone number, voice mailbox, and extension for all your registered phones at no additional cost.
How Multiple Devices on One Extension works
As long as a phone is connected to the internet, it can be located by a phone system that uses IP telephony, and thus receive calls at the appropriate extension number. With Multiple Devices on One Extension, each extension can register up to three different IP addresses to connect a call.
