Wondering how to configure FXS analog port in just few minutes? Here’s How.

If you want to configure your FXS analog extensions without any special configurations, here how I do it. It will simply ring each port’s extension.


I have AudioCodes Mediant 1000 with 4 FXS analog ports attached to it. I simply want to ring each port. I use 5001, 5002, 5003, 5004 extension respectively. Configuration of digital interface is not part of this post.


Directly go to Trunk group and configure below:


Configure Trunk Group Settings as below:


Configure the Tel to IP routing.

This route is basically the call from analog ports to M1K IP address.

  • Source number: Any
  • Destination number: 5xxx# (4 digits start with 5)
  • Destination IP address: (AC M1K IP address)
  • Destination Port: 5060 (This was my Destination Port configured in SIP General Parameters)


Configure the IP to Trunk Group Routing.

This route is from AC M1K IP address to analog ports.

  • Source number: Any
  • Destination Prefix: 5xxx#
  • Destination Trunk Group: 2


No need to configure anything at manipulation table.


Call from 5001 to 5002 was indeed working and was able to answer.


That’s it!!!

Easy. Isn’t it? 🙂

Hope it helped you!
