Appendix B - Troubleshooting The following are common problems associated with the phone and possible solutions. Problem Possible Solution(s) Network Disconnected message The Network Disconnected prompt appears on the display and the telephone status lamp turns on if phone is not properly connected to the network. The phone also displays the default time and date of 12:00 am Jan 1st, 2005 or the equivalent. Check that the cables are tightly connected to the phone and to the wall jack. The phone should automatically detect when it is reconnected and will display the "Network Connected" prompt for a few seconds. However, if changes have been made to your phone's network settings, you may need to restart your phone. Contact your system or network administrator for assistance. Why is my display blank? Ensure that power is being provided to your phone. If your network does not provide inline power over Ethernet, you can obtain an additional accessory, the Aastra PoE (Power over Ethernet) inline power supply, to provide power over Ethernet locally to your phone. See the section "Connecting to the Network and to Power" in the Aastra Model 6731i Installation Guide for details. Why is my speaker not working? Why can't I get dial tone? Why doesn't my phone ring? Why is the lamp not coming on when I have a new Voicemail Message? If you press the Speaker key and the speaker lamp flashes and you do not hear dial tone through the speaker, the Set Audio option in the phone's Options list has been set up for headset use. Press the Speaker key a second time and if the lamp goes out, the phone has been set up to be used only with a headset or handset. If the lamp stays on steady and you hear dial tone, the phone has been set up so that you can alternate between the speaker and the headset by pressing the Speaker key. Check for any loose connections and that the phone has been installed properly. For installation instructions, refer to the "Installation and Setup" section in the Aastra Model 6731i Installation Guide provided with your phone. Check the ring volume on your phone. It may be turned down or turned off. To adjust the ringer volume setting, press the volume key when the phone is on-hook and idle. For more information, see Volume Key. Your phone system or service provider must provide a Visual Message Waiting service for this function to work. Contact your system administrator. Why is my handset not working? Check to ensure that the handset cord is fully connected to both the phone and handset. The handset connection on the bottom of the phone is marked with the handset symbol . How do I find the IP address This setting is in the Options list. See IP and MAC Addresses in of my phone? Appendix A. How do I change my User Password? This setting is in the Options list.
