Re-Registering the 5505 Guest IP Phone

The 5505 Guest IP Phone will require re-registration when the DN is changed for the phone 
and/or when the User PIN is changed.

To re-register the phone:

1. On the 5505 base station, press down the Volume Up/Down key on the base station.  
2. Then release the Volume Down ( -) portion. 
3. While the Volume Up key is pressed, type 734 (REG) to start the re-registration 

process.

 The Line in Use keys start flashing slowly waiting for the DN number and Registration 
PIN.

4. Enter the DN and registration PIN as DN#PIN#. 

5. Press the Speaker key.

 

If an invalid DN or invalid PIN is entered, the cordless handset will display DN followed by 
!REG or ! for DNs, indicating that the phone is not registered. Try the registration again.  
See “Maintenance and Troubleshooting” on page 39 if the procedure is unsuccessful.

After successful registration, the screen displays the Room Name/Number.

6. At any time, to exit from the re-registration mode, press the End Call key 

  on 

the 5505 base station.

Firmware Upgrades

The 5505 IP Phone checks its tftp server every day at 3 a.m. If there is new firmware, the phone 
performs an upgrade.

If the phone is on a call at 3 am, it waits until it is idle before doing the firmware check.
