5 Configuring FRITZ!Box Fon WLAN for Telephone Connections
MSNs Are Configured in the ISDN Telephone
z
If you specify an Internet number as the outgoing MSN
in the ISDN telephone, outgoing calls will be conducted
over the Internet.
Internet numbers can be set up in the ISDN telephone
just like MSNs.
z
If you have entered only fixed-line numbers as MSNs in
the ISDN telephone, all calls will be conducted on the
fixed-line network. If you want to use Internet telepho-
ny, you must replace an MSN with an Internet number.
See the documentation of your ISDN telephone for instruc-
tions on setting up MSNs.
In FRITZ!Box Fon WLAN you can enter additional Internet or
fixed-line numbers, which can then be assigned to the ISDN
telephones. A list of all registered numbers is displayed after
selecting “Telephony / ISDN Terminal Devices” in the menu.
All of the MSNs set up in the ISDN terminal devices must al-
so be entered in FRITZ!Box Fon WLAN.
