NOTE: We strongly recommend you do not use this option for your phone extensions. Use instead analog telephone adapters, or a channel bank. If you choose to use Analog Phone extensions with phones physically plugged into Switchvox, those phones will not be able to take full advantage of the Switchvox features. |
Virtual Extension. An extension without a phone or a Switchboard. This type of extension behaves like a SIP Phone extension except it does not have a Switchboard and it does not show the phone as Unreachable in System Status. This is useful as a general voicemail box.
