Cordless telephone constantly indicates received calls
The display of your FRITZ!Fon and/or a cordless telephone from another manufacturer keeps indicating that you received calls from one of your own telephone numbers, although you did not receive calls from this number. The word "EMAIL", "FAX" or "VOICE" may be displayed in front of your own number.
- Since your telephony provider supports MWI (Message Waiting Indication), these calls indicate that you have new messages in your mailbox.
Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.
Disabling MWI in the FRITZ!Box
In your telephony provider's online customer center you can configure whether and how you are notified when new messages arrive. Normally, the signaling stops as soon as you have listened to all of the messages. Information on the mailbox and MWI signaling can be obtained from your telephony provider. You can disable MWI in the FRITZ!Box if you are receiving these messages because of calls to an internet telephone number and they bother you:
- Click "Telephony" in the FRITZ!Box user interface.
- Click "Telephone Numbers" in the "Telephony" menu.
- Click the (Edit) button for the respective internet telephone number.
- Select "Other provider" from the drop-down list.
- Disable the option "Provider supports MWI (RFC 3842)". If the field is not displayed, enable the Advanced View.
- Click "OK" to save the settings.
