What kind of Extensions require Subscriptions?

You may already be familiar with Switchvox and all of the different "Extension Types" that you can create inside the system. It is important to note that you do not need a Subscription for every extension you create inside your Switchvox.
Here are all the Extension types that require a Subscription:

• SIP Phone or SIP Adapter for Analog Phone (ATA) - Any SIP phones, like Polycom SoundPoint phones or a SIP softphone. Also any Analog Telephone Adapter such as a Sipura SPA-1001
• Analog Phone - This extension type is for regular analog telephones that are physically plugged into the PBX via an FXS port
• Virtual Extension - Virtual Extensions are extensions for users without a phone. They can be used for voicemail boxes, or can be set up with call rules that always cascade to the user's cell phone. They behave exactly like SIP Phone extensions except they do not show the phone as "Unreachable" in the System Status screen.

Am I missing the free part? Can a Grandstream of PAP2T be configured as an extension?

Maybe this topic should be in BYOD?

Maybe PBXinaFlash is better?
