Can I Connect an IP Phone to an Analog PBX?

Q: We have an old digital NEC IP PBX. We are trying to find a way to allow remote users to use IP phones to connect to our phone system as analog extensions. Can I connect an IP phone to an Analog PBX through an FXO gateway? Is there a device that allows IP phones to connect to it, and then hand them off to the phone system as an analog extension?

A: Unfortunately, no. You will need SIP Service to run voice over IP and SIP Service is provided from a provider, not a device. An FXO gateway is for IP Service coming into an analog device. an FXS gateway is for an IP PBX to connect to an Analog endpoint.
