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.
Why does my phone display the “No Service” message?
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.
Why does my phone display "Bad Encrypted Config"?
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.
