Troubleshooting

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. 

The phone displays the “No Service” message if the SIP settings have not been set 
up correctly.

The Registrar server could be set to 0.0.0.0. A global value of 0.0.0.0 disables 
registration. However, the phone is still active and you can dial using 
username@ip address of the phone. The phone displays "No Service".

If the Registrar IP address is set to 0.0.0.0 for a per-line basis (i.e, line 1, line 2, 
etc.), then the register request is not sent, the "No Service" message does not 
display, and the message waiting indicator (MWI) does not come on.

Check that the "Registrar Server" IP address in the Aastra Web UI at Advanced 
Settings->Global SIP is correct. Check the "sip registrar ip" parameter in the 
configuration files is correct.

The IP phone displays "Bad Encrypted Config" because encrypted configuration 
files are enabled but the decryption process has failed. Specific cases where 
decryption fails are:

Reason:

The site-specific password in security.tuz does not match the password used to 
encrypt the <mac>.tuz or aastra.tuz files.

Fix:

Encrypt the .cfg files to .tuz using the correct password, or replace the security.tuz 
with the correct encrypted file.
