Configuration information for a Cisco 2811 running IOS IP Voice 12.4.24T

Cisco Configuration Info for IOS 12.2

The following configuration file example is known to work when configuring sipX with a Cisco SIP Gateway FXO setup. You must replace parameters within the file (e.g., ip address 10.1.##.# 255.255.###.#) with your site specific parameters when you copy the file through a terminal window into the Cisco Gateway.

  1. Copy the following example, starting with the first exclamation point (warning) and ending with end (end).
  2. Open a terminal window/telnet to the Cisco gateway.
  3. At a command prompt enter the Write to Screen command (e.g., Cisco#wr t) after gaining access through protected mode (enter the "enable" command at a command line prompt to enter protected mode and a # sign displays with the prompt) and a similar configuration displays.
  4. Type the config command to enter an editable mode and copy the file example into the Cisco gateway.

Enabling FXS interface registration on Cisco SIP gateway:

if you plan to use your Cisco device as both a gateway and for registered FXS users, you must create explicit custom rules in your dialplan for your FXS users otherwise sipXpbx authorization subsystem will not allow calls to your users on the Cisco device. That is because they share the same IP address as your gateway.sip-ua
