Phone and Virtual Extensions

The settings are mostly the same for SIP phones, Analog phones, and Virtual extensions. These extensions have a corresponding Extension Suite account (/main):

• SIP Phone or SIP Adapter for Analog Phone (ATA). A SIP phone, or an analog phone plugged into a SIP Adapter (e.g., Sipura SPA-1001).

• Analog Phone. A regular phone (not VoIP/SIP) that is physically plugged into the Switchvox server. This is an appropriate extension-type for a fax machine or an intercom.

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.
