But those who hope that these features can also be used with an ISDN telephone at the Fritz box, will be quickly disappointed: all comfort features of "Fritz" portables are realized exclusively via DECT. The box does not have the appropriate communication channels to enable the integration features offered by ISDN system telephones can. Since you will not find a single ISDN device, and that was me - thanks to research in Internet forums - even prior to purchase of the »elmeg« -device already clear. Nevertheless, the hope, in some respects - to be operated with an ISDN device better than with an analog extension (which had to be replaced) - as in the use of PC-based telephony via the TAPI driver.
I have an additional key module (black blue Elmeg T400 / 2 Function Key Expansion Module) bought this phone and connected to the S0 bus of the "Fritz! Box 7390". Also, I have connected the phone via a USB cable with the Windows 7 computer (32 bit) and the supplied "WIN tools" installed for the phone. This gave the following experiences were:
1. The new ISDN extension with this phone could be easily set up in the Fritz box.
2. The USB installaion the phone was hakelig: The first step is the waiting in the download area of "elmeg" Web page USB drivers to download and unzip. After the phone connection Windows will logically once no suitable driver when you have not just copied the * .inf files from the downloaded and unzipped driver into the Windows system directory. After the first failed installation of the telephone entry "Computer" in the Start menu is to click with the right mouse button and "to choose from the context menu Managing". In the dialog you can find the "Device Manager" and this is an entry for the »elmeg« -Telephone with an exclamation mark in front of it. After double-click it to open the Properties window. Update on the tab "Driver" and after clicking the button "Driver" there is the possibility to install the Funkwerk driver, indicating the storage location of the * .inf files on the hard disk after. This installation worked smoothly.
3. The installation of the "Win Tools" even functioned smoothly and their communications with the phone via the USB port worked right away.
4. Phone number management program (the "comes with the phone Win Tools") was able to accomplish not import a converted Fritzbox Phonebook. This I had with the external Freeware »Contact Conversion Wizard" in different formats (* .csv, * .vCard) converted. Ultimately, only remained to transfer the entire phone book Fritzbox via the Windows Clipboard (Copy, Paste) manually. But that's still more comfortable than anything having to manually enter the phone (as it would be for devices without USB interface the case).
5. When a call stored in the phonebook of Fritzbox contact names appear (should be self-evident, which can even modern terminal to the analog ports of the box).
6. The selection of a certain (non-default) MSN via the phone menu for outgoing calls will also work on the Fritz box. So you need not to select the of the Fritz box designated prefixes. Likewise, it works, if you assigned function keys with the function "MSN" (then look only no. From Tel-book or enter and establish a connection via the correspondingly programmed function key).
7. backlight of the display: is so weak that you can not see under fluorescent light in the room, only in the dark or in low light.
8. power to the phone: Only possible via the S0 bus, there has been no input for a separate power supply. The Fritz box can power a single ISDN device with power; leaving you enough - as a positive effect - a transformer plug less.
Not at the Fritz box anyway - 8. All diodes on the function keys lights seemingly only in conjunction with a "elmeg" TK-plant. That does the stored functions (speed dial, MSN assignment, keypad dialing, etc.) could not be stopped. Exception: When the headset is connected and assigned to a function key with "Headset on / off" this LED lights; as incoming calls are signaled via the corresponding diode.
9. Using an external (existing) Headsets - in this case the brand "call vice" of a warehouse from Buggingen - was no problem. So you have to buy a system from the manufacturer's recommended headsets to not necessarily.
Finally, a word on PC telephony with the equipment: The use of AVM TAPI driver (for Fritz box properly) to work with the phone though (just like the dialer of the box), it can be uncomfortable. In the phone's display is blank, you can pick up the handset of the phone only after the initiation of the connection setup on the PC the same. The supplied by the manufacturer of this phone TAPI driver is much better, its installation (easily parallel to the AVM TAPI possible) is recommended. It carried out status messages on the display. In addition, you can select when using the phone freeware "Phoner" in this one of the configured in the phone MSNs as the outgoing MSN (via a drop-down menu). When using the AVM TAPI this DopDown menu remains empty, because AVM is not supported.
Conclusion: The commissioning of the phone (including software installations, various Funktiosntests and customize the labels for the function keys) was with me, in spite of prior knowledge, time consuming. However, the replacement of analogue extension was worth against the ISDN extension with this phone, especially as the PC-based telephony is so comfortable. I type numbers that I read somewhere on the PC (for example on websites) and need, not you up, but let them prefer to choose directly. Otherwise there are no major advantages over the analog extension - just mainly that choosing the numbers with ISDN is much faster, and that has direct keys "are available through the Zuatz-key module more». Who said points are not important, which is connected to an analog phone as a desk phone to the "Fritz! Box 7390" as well served and not have to invest in expensive ISDN technology.
