Driving a 12V DC relay

[IT 24-7]

Hi,

we need to open an electric doorlock from the pbx/phone that is driven by a 12VDC relay. What 3CX SIP devices do you know for this?

Thanks

I would suggest one of the Door Entry phones:

They don't supply power but do close a contact to trigger a door release.

No we need to drive an existing system.

Some door phones have a built in web API you can invoke to unlock the door. Others use a proprietary network protocol to unlock the door. If it has a web API, you can invoke that directly from a CFD. If you need to invoke a proprietary solution, create your own web API that in the code behind invokes the proprietary command and call that from the CFD.

I'^m think to use a Fanvil PA2 to drive a relay to open the door.
Anyone has experience?
