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.

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.

Connectivity Issues

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

Note: If connecting to Cloud UCX, then all phones are considered to be remote phones.

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 packet capture on the UCX Server, disconnect and reconnect the network cable to the phone. Stop packet capture. Review packet capture for cause.

Audio and Display Issues

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)
