Hi Dean; I saw this on the Taug forum and thought I might be able to help. You could try putting the phone in Recovery Mode and reloading firmware. Recovery mode and new firmware is a full factory reset. I pulled the following from the Administration Guide:
You can force the IP phone into recovery mode by pressing the 1 and # keys during boot up when the logo displays. Why does my phone display "Application missing"? If you have experienced networking issues while the phone was downloading the application from the TFTP server, it is possible that the phone can no longer retrieve the required firmware file. In the event that the phone is no longer able to communicate with the TFTP server in its attempt to re-download the firmware and the phone cannot locate the application locally, the message "Application missing" displays. The phone also displays the following: "Recovery web-client at: <IP Address>". The IP Address displayed is the IP address of the phone. If the phone is unable to receive an IP from the DHCP server or has lost its record of its static IP, the phone auto-assigns itself the default IP 192.168.0.50. To recover the firmware for your phone in this circumstance, please perform the following: 1. Launch your web browser on your computer. Note: Your computer needs to be on the same network as your IP Phone. 2. In the URL, type: "http://<IP Address>" (where IP Address is the IP Address displayed on the phone). Your browser launches the Aastra IP Phone Firmware Recovery page. 3. Call Customer Support and request a <phone model>.st file. 4. Copy the file to your TFTP server. 5. Enter the <phone model>.st file that is ready for download. 6. Enter the IP address or qualified domain name of the TFTP server. 7. Press the Download Firmware button. Please ensure that the TFTP server is running and accessible on the network. If the firmware file is correctly located on the running TFTP server, the phone will locate the file and reload the application onto the phone. Hope this helps!

I have a couple of phones that this same thing has happened. After a power failure, the handset won't function. You can hear callers, and talk to callers through the speaker phone but if you use the handset they can not hear you. you can hear them though. I have tried new firmware, old firmware, factory defaults and nothing. I know the phone is not completely the issue because I can use the headset or speaker phone and it works. I heard sometime ago, there was a way to reload the base boot rom and that would fix it. I have just never been able to find a solution or instructions. Any Idea's? --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected] --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
