I recently bought a Fritz!Box 7390. Main reason was that I wanted to integrate telephony (POTS) in my daily workflow on my Mac.

In this article I will describe the configuration and add-ons I installed.

I wanted to use the Fritz!Box as part of my existing network. I decided not to use the WLAN option of the Fritz!Box, but instead I bought a Fritz! Powerline 520 E set, because I did not have a cabled network connection on the location where the Internet modem was located. In this setup I could connect the Internet modem to the LAN 1/WAN connection of my Fritz!Box.

DECT telephone device

The Fritz!Box 7390 offers a basestation, upto 6 DECT telephones can be connected.

Note: For now I do not have any DECT phones connected.

Update: Some developments here. I bought a DECT Gigaset A420A TRIO. When they are setup I will update my findings.

VOIP telephony

For OSX there are several softphone apps available:


Counterpath X-Lite


Alfred workflow

I created a simple Alfred 2 workflow that calls the Frizzix dial helper.

Use keyword “Dial” to trigger a little Applescript that contains:

on alfred_script(q)
    set TelNumber to q as string
    set Tel to ""
    repeat with each in TelNumber
        if "+1234567890" contains each then set Tel to Tel & each
    end repeat
    tell application "Frizzix"
        dialInstantly Tel
    end tell
end alfred_script

Call diversion from script

I also installed:

  • the Address Book Plugin

  • Services plugin

Note: it seems that in my setup phone numbers are recognized in webpages, but dialing out does not work.
