What to do if extensions (except IP-PT/ SIP phone) do not operate on Panasonic PBX?
- T
  Todd Palmer DVMAug 29, 2025
  Several issues could be at play. The extension card might be defective, and require replacement. There could be a poor connection between the PBX and the extension, take the extension and plug it into the same extension port using a short telephone cord. If the extension works, then the connection between the PBX and the extension must be repaired. If a telephone with an A-A1 relay is connected, ensure a 2-wire cord is used and that the A-A1 relay switch is in the 'OUT' or 'OFF' position. Lastly, the extension itself might be malfunctioning, take the extension and plug it into another extension port that is working. If the extension does not work, replace the extension.

What to do if the LINK indicator of the mother board does not turn on Panasonic KX-NS500?

  This could be due to a few reasons. The mother board itself may be malfunctioning and require replacement. Check for a poor connection, ensuring you are using an 8-pin twisted pair cable and that any CAT 5/CAT 5e cables are not exceeding 100m in length, also make sure that a straight cable is used for connection to a switching hub. Finally, a network malfunction may be the cause, so ensure all network devices are switched on.

Why are my IP-PTs or SIP phones not working on my Panasonic KX-NS500 PBX?

  There are several possible reasons: The DSP card or the mother board might be malfunctioning, consider replacing them. It could be due to insufficient activation keys, purchase additional keys from a certified dealer. The IP-PT/SIP phone may not be registered, so register it. The phone itself might be faulty, try replacing it. Check for a poor connection, ensure you're using an 8-pin twisted pair cable, CAT 5/CAT 5e cables under 100m, and a straight cable for the connection to a switching hub. Also, ensure all network devices are on and the IP-PT/SIP phone isn't blocked by a firewall or other network devices.

  Several factors can cause this issue. It could be a DSP card malfunction, requiring you to replace the card. Alternatively, the mother board might be malfunctioning, necessitating its replacement (remember to turn off the PBX first). Ensure you have enough activation keys; if not, purchase additional keys from a certified dealer. Check for poor connection: use an 8-pin twisted pair cable, ensure CAT 5/CAT 5e cables are under 100m, and use a straight cable for switching hubs. Finally, verify that all network devices are on and that no unwanted firewall is blocking the IP network.
