What does the Grandstream 502 (HandyTone 502) do?
You can connect two analog telephones or fax machines to a voice over IP network with the Grandstream 502. The Grandstream 502 is an analog telephone adapter that includes two FXS ports and two Ethernet ports. Each FXS port allows either a traditional analog telephone or fax machine to be connected. Each Ethernet port is an RJ45 connection to the IP network. The The 502 converts the traditional analog signals into IP (digital) signals which is why it is called an adapter.
