      If you cannot enable features using Feature Access Codes on your Mitel IP Phone, it might be because the feature is not enabled for your handset. Contact your System Administrator and ask to have the feature enabled. Alternatively, your system might not use the default Feature Access Codes. In this case, you should contact your System Administrator for a list of the supported Feature Access Codes for your system.

    What to do if Mitel Accessories cannot make calls and VoIP indicator is off?
    • S
      smithluisSep 4, 2025
      If you cannot make calls, and the VoIP indicator is off, it might be due to your router blocking Internet telephony or needing a firmware update. * To resolve a blocked connection, first try disabling STUN in the Internet settings menu, then reset the base station. If that doesn't work, configure port forwarding, using static IP mode. The default SIP port is 5060, and the default RTP port is 5004. * To update the firmware, refer to your router's user manual.
