Figure 1: Diagram of MaxCS, Firewall/NAT, and AudioCodes gateway
Prerequisites
To set up analog extensions using an AudioCodes MP-11x or MP-124 gateway, you must meet the following require-
ments:
•
You must be running either MaxCS Release 7.0 Enterprise or MaxCS Private Cloud.
• Proper configuration for MaxCS behind NAT is required (including the port forwarding and Enterprise Manager
settings). Any AltiGen IP phones behind NAT should already be working correctly behind the on-premise firewall.
• The AudioCodes gateway must already have a static IP address and must be able to be configured through the
web interface.
• Make sure that your AudioCodes gateway is running the correct version of firmware: Click the Home button and
check that you have firmware version 6.60A.265.010 or later.
• You must have a valid MaxCS 3 rd -party SIP license to implement analog support.
IMPORTANT! If you plan to have your MP-118 gateway support both FXS and FXO, we recommend that you to
configure your analog extensions first, and then configure survival mode. A proxy group is required
when you are running both FXS and FXO on the same gateway.
