How to obtain the MAC address of a phone when the phone is not powered on?
Three ways to obtain the MAC address of a phone:
You can ask your supplier for the shipping information sheet which includes MAC
addresses according to the corresponding PO (Purchase Order).
You can find the MAC address on the label of the carton box.
You can also find the MAC address from the phone’s bar code on the back of the
phone.
Why can’t I get a dial tone?
Check for any loose connections and that the phone has been installed properly.
For the installation instructions, refer to Phone Installation on page 11.
Switch between the Handset, Headset (if present) or Hands-Free Speakerphone to
check whether the dial tone is present for one of the audio modes.
If the dial tone exists on another audio mode, connect a different handset or
headset to isolate the problem.
Why doesn’t the phone ring?
Check that the ringer volume on the phone. To adjust the ringer volume setting, press
the Volume key when the phone is idle. For more information, refer to Volume on page
27.
Why can’t I receive calls?
Check that the SIP registration with your system administrator.
Check that the DND (Do Not Disturb) mode is deactivated on the phone. Refer to
Do Not Disturb (DND) on page 79.
Check that call forward is disabled on the phone. Refer to Call Forward on page
83.
Check whether the caller number is stored in the blacklist directory. Refer to
Blacklist on page 41.
Why is my handset not working?
Check that the handset cord is fully connected to both the handset jack on the phone
and handset. Refer to Phone Installation on page 11.
