Below is a table that describes common issues relating to base stations and handsets:

Common Device Issues and Troubleshooting

Problem: Cause of problem: Solution:
Base station light is solid red and there is no connectivity in nearby area.
The base station can't get an IP address.

1. Verify that the Ethernet cable is securely attached to the base station.

2. Verify that the Ethernet cable is not faulty.

3.Contact the DoIT Helpdesk for further support.

Base station LED flashes red and handset displays "No SIP Reg" message.

Or

Handset has one or more of the following:

  • Red "X" in the signal indication area
  • Yellow signal bars/1-2 signal bars in the signal indication area
  • Audio is coming in as garbled/dropping audio
  • Handset displays "Searching" message
The handset has lost communication with the base station/Phone is out of reach of base station signal.

1. Attempt disconnecting and re-registering by going to Settings > Connectivity > Deregister > enter deregister pin (0000), then going to Settings > Connectivity > Register and enter the AC of the network. (Should be 1234).

2. Walk around the vicinity of the work area and see if you receive better signal from the base stations. If you are able to receive better signal it may be that you had walked outside of the coverage zone. If you believe that the area with bad coverage should have coverage and is not working correctly, contact the DoIT Helpdesk for further support. 

Handset is "popping" during call while end user is moving around the coverage area. Handset is roaming between base stations.

This occurs when the handsets are roaming from one base station to another, this is a normal function of these devices. There should be no impact other than a brief delay in the audio stream. No further action should be needed.

If the popping is excessive or is impacting the call quality to the point where they cannot continue the call, contact the DoIT Helpdesk for further support.

Handset won't turn on.

Or 

Handset won't stay on.

The battery doesn't have sufficient charge, the plastic tab over the battery contacts aren't removed, the battery has failed, or the device is faulty.

1. Verify that the plastic tab is removed from the battery by turning the lever on the back plate of the phone to the unlock position, and lifting up on the back plate. If the plastic tab is still there, it will have red arrows to show you how to remove it.

2. Try swapping out the non functional battery for a functional battery from a different handset if one is available. If it works, try putting the non functional battery back in and putting it on a charging station.

If the non functional battery turns on while on a charging station, the battery just needs to be charged.

If the handset works with a different battery, and the battery in question does not work even when trying to charge it, the battery has gone bad and needs to be replaced.

If both batteries in the above scenario don't work in the faulty handset, but seem to work on other functional handsets, the handset itself may be faulty. 

In any of the scenarios where new equipment is required, contact the Network Applications VoIP team for further information on ordering the equipment.

Handset doesn't respond to key presses. Keypad is locked. 1. Press and hold the star (*) key for 2 seconds to unlock the keypad. 
Handset beeps constantly while on the charger. Handset is not fully seated on charging station, plastic cover over the battery was not removed, or the battery is faulty.

1. Ensure that the handset was placed in the charger so that the contacts on the handset and charger fully touch.

2. If the handset is new and this is the first time it has been placed on the charger, check that the plastic on the battery has been removed.

3. If none of the scenarios apply, the battery may be defective. If available, put a battery that is verified as working into the handset and place the handset in the charger. If the handset doesn’t beep, then the original battery is defective.

In any of the scenarios where new equipment is required, contact the Network Applications VoIP team for further information on ordering the equipment.

 If the steps taken have been completed and an issue still persists, try resetting the handset by going to Menu > Settings > Reset Settings. Press "Yes" to confirm the reset and enter the pin (0000)

All other issues otherwise listed should be documented in explicit detail and then escalated to the DoIT Helpdesk for further support.
