Configuring Analog Extensions with AudioCodes Gateways Page 3 of 25
About This Guide
This guide explains how to configure one or more analog extensions using an AudioCodes VoIP SIP MP-11x or MP-124
gateway.
These instructions will work behind most on-premise firewalls, NAT routers, and EdgeMarc SBCs. MaxCS and the
AudioCodes gateway can be on the same LAN or can be inter-connected via VPN.
The examples in this guide illustrate the configuration for an AudioCodes MP -118 gateway. Refer to the documenta-
tion for your gateway model as needed (to find your AudioCodes user manual, search for “LTRT-65417 MP-11x and
MP-124 SIP User’s Manual Ver 6.6.pdf” in your web browser).
This guide comes with two files. (These two files can be found in the AltiGen Knowledge Base, along with this guide.)
Store these files locally; you will need to upload them into the AudioCodes configuration tool during the procedures
in this guide, in the section Verification .

Introduction
When configured, MaxCS treats analog extensions behind an AudioCodes gateway as 3 rd -party IP phones. The analog
phones connect to an FXS port. The FXS port converts the analog signal to SIP.

• MaxCS – 10.40.1.43
• Firewall/NAT WAN – 10.40.0.95
• Analog extension – 167
