2.0 Collect Basic Information

• What is the phone model? (5004 / 5006 / 5008 / 5010 dark faceplate / 5010 light faceplate / 5010W)
• What firmware type is running on the phone - SIP or XSTIM?
• What is the firmware version on the phone?
• What is the UCX Server platform? E.g. UCX Cloud, Virtualized Server, Galaxy Mini, Galaxy 250, Galaxy Expand, etc.

3.0 First Steps

• Check when was the UCX Server last updated. Perform a software update on the UCX Server to make sure it is on the latest software.
• Check if the phone(s) are on the latest firmware version (see Infinity 5000 Series - Firmware Distribution). Update the phones to the latest firmware.

4.0 Connectivity Issues

XSTIM - The phone has problems connecting or staying connected to the UCX.

REMOTE phones:

• Login to UCX web-based configuration utility and check the following:
  • Go to PBX -> PBX Configuration -> Nortel Settings page, check the Public IP field, make sure it is correctly set to the public IP of the UCX Server. (See SIP Settings page on how to auto-detect the public IP address.)
  • Also check the Port field, take note of the Port number.
• Confirm the customer's router is configured to forward the correct Port number to the IP address of the UCX Server. (See Configure Port Forwarding for Remote Access.)
• Login to the phone menu:
  • Check the S1/S2 address is set to the Public IP address of the UCX Server
  • Check the S1/S2 port is set to the correct Port number.
• If all configuration looks correct, try replacing the network cable.
• Connect the phone from a different location with internet.

LOCAL phones:

• Login to UCX web-based configuration utility and check the following:
  • Go to PBX -> PBX Configuration -> Nortel Settings page, check the Port field, take note of the Port number.
  • Go to System -> Network page, check the IP address for ETH0 and ETH1. Find out if phones are connecting to ETH0 or ETH1.
• Login to the phone menu:
  • Check the S1/S2 address is set to the correct IP address for ETH0/ETH1.
  • Check the S1/S2 port is set to the correct Port number.
  • Set the Retry Number to 3 or more.
• Confirm how IP address is assigned to the phone. E.g. DHCP, Static, VLAN etc. Take note of the IP address of the phone.
• Check if the phone and UCX Server belong to the same subnet.
• Connect a computer to the same subnet, try pinging the phone's IP address and the UCX Server's IP address.
• If all configuration and network setup looks correct, try replacing the network cable.
• Start a packet capture on the phone as follows:
  • Log into the phone's web interface by point a web browser to the phones IP address with username: admin and its password (default admin)
    
  • Click Sign in
  • Click on the Management heading to navigate to the Management page
    
  • Click on the Tools sub-menu on the left-hand side of page
    
  • To start a packet capture, (Pcap Feature), click on the Start button
    
  • To stop the packet capure, click Stop
    
  • Download the packet capture (a ".pcap" file) to your PC by clicking on Export which opens a standard file saving interface
    
  • Subsequent captures will erase the current .pacp file on the phone
• To Start packet capture on the UCX Server, disconnect and reconnect the network cable to the phone. Stop packet capture and download.
• Review packet capture(s) for cause.

Expansion Module has problems connecting to the phone

• Disconnect expansion module(s) from the main phone.
• Login to the web interface of the phone (5010 or 5010W).
• Navigate to Management -> Auto Provision page.

If the phone is experiencing audio issues like one-way speech path, no dialtone or intermittently losing audio on speaker, perform a factory reset of the phone.

If the labels or text are not displaying correctly, cut-off, misplaced or has extra unwanted information, perform a factory reset of the phone.

(XSTIM factory reset / SIP factory reset)

6.0 Retrieving Syslog from Expansion Module

To obtain the IP address of the expansion module, perform the following steps:

• Press the LEFT navigation key on the expansion board three times, and then press and hold the RIGHT navigation key for 10 seconds.
• After releasing the key, the administration Menu will be displayed on the screen.

• Press the LEFT navigation key to exit the menu.

To retrieve the system log file, perform the following steps:

• Set the IP address of your computer to a static IP address in the same subnet as the expansion module, 172.20.167.X (cannot conflict with the IP address of the expansion board).
• Connect a network cable from the computer to the Uplink port of the expansion board (the expansion board will need to be disconnected from the phone).
• From a web browser, enter the IP address of the expansion board.
• Navigate to Management - Configuration page, click to Download the system log.
