trace, locate the call to determine if it was blocked intentionally by a route pattern or the calling search space, or by any other configuration setting.

4.Reorder tones can also occur when calling through the PSTN. Check the SDI trace for Q.931 messages, in particular, for disconnect messages. If a Q.931 disconnect message is present, it means the other party caused the disconnect and we cannot correct for that.

Gateway Registration Problems

One of the most common issues encountered with gateways on a Cisco CallManager is a registration problem. Registration can fail for a variety of reasons.

This section deals with two similar but different categories of gateways. The Analog Access AS-X, AT-X and Digital Access DT-24+ and DE-30+ belong to one category. These gateways are stand-alone units that are not directly connected to a Network Management Processor (NMP). The second category includes the Analog Access WS-X6624 and Digital Access WS-X6608. These gateways are blades installed in a Catalyst 6000 chassis with direct connectivity to the NMP for control and statusing.

In the examples below, we have bolded lines of text to make it easier for you to see the messages being explained. In the actual display output, text is not bolded. The examples are from an WS-X6624.

The first thing to check is that the gateway is up and running. All of the gateways have a “heartbeat” LED that blinks 1-second on, 1-second off when the gateway software is running normally. If this LED is not blinking at all, or blinking very rapidly, then the gateway software is not running. Normally this will result in an automatic reset of the gateway. Also, it is normal for the gateway to reset itself if it cannot complete the registration process after about 2 to 3 minutes. So you may happen to look at the heartbeat LED while the device is resetting, but if the normal blinking pattern does not appear in 10 to 15 seconds, then the gateway has suffered a serious failure. On the AS-X or AT-X gateway, the heartbeat LED is the far right green LED showing on the front panel. On the DT-24+ or DE-30+ gateway, it is the far left red LED on the top edge of the card. On the Analog Access WS-X6624, it is a green LED inside the blade (not visible from the front panel) on the far right card edge near the front. Finally, on the Digital Access WS-X6608 there is a separate heartbeat LED for each of the 8 spans on the blade. There are 8 red LEDs across the card (not visible from the front panel) about 2/3 of the way towards the back.

The second thing to check is that the gateway has received its IP address. A standalone gateway must receive its IP address via DHCP or BOOTP. A Catalyst gateway may receive its IP address by DHCP, BOOTP, or by manual configuration through the NMP. If you have access to the DHCP server, the best way to check a standalone gateway is to verify that the device has an outstanding lease on an IP address. If the gateway shows up on your server, this is a good indication, but not definitive. Delete the lease at the DHCP server, and then reset the gateway. If the gateway reappears on the server with a lease within a couple of minutes, then everything is working fine in this area. If not, then either the gateway cannot contact the DHCP server (Is a router improperly configured and not forwarding DHCP broadcasts? Is the server running?), or
