Receive Inbound Calls on an Analog Phone Connected to a TA1600/2400/3200 FXS Gateway

Once your Cloud Voice system and a TA1600/2400/3200 FXS gateway are connected, incoming calls can be delivered all the way to an analog phone plugged into the gateway. This lets a traditional handset, fax machine, or overhead pager act like any other extension on the phone system.

An FXS (Foreign Exchange Station) port is the port on the gateway that supplies dial tone to an analog device. Each FXS port registers to Cloud Voice as an extension, so to make an analog phone ring on an incoming call you point an inbound route at that extension.

Note

This guide covers only the inbound routing. It assumes the gateway is already linked to Cloud Voice and that one of its FXS ports has already been registered as an extension. If that is not done yet, complete the gateway connection first.

Step 1. Create an inbound route

An inbound route decides where calls arriving on a trunk (the connection between Cloud Voice and the outside phone network) are sent. Here you send them to the extension tied to the gateway’s FXS port.

1. Sign in to the Cloud Voice portal and go to Call Control > Inbound Route, then click Add.

2. Fill in the route settings:

   • Name: A label that identifies this route. Use something descriptive, such as the analog device or location, so it is easy to find later.
   • Trunk: The trunk that incoming calls arrive on.
   • Default Destination: The extension registered to the FXS port. This example uses extension 1000.

   

3. Click Save, then Apply.

Caution

The Default Destination must be the same extension number that the FXS port is registered as. If it points at a different extension, the analog phone will not ring. The FXS extension also needs to be registered and online, or the call has nowhere to land.

Tip

The route takes effect only after you click Apply. If a test call does not behave as expected, confirm you applied the change rather than only saving it.

Step 2. Place a test call

Dial the trunk you selected in Step 1. The analog phone connected to the FXS port registered as extension 1000 should ring, confirming the inbound route is working.
