Of course, should not expect too much you. The build quality is poor (piano lacquer, worse buttons, sensitive color display ...)
For this you can use this part but finally "clean" upgrade to Voice over IP, and this is now the standard. The device is next to analogue and ISDN also a "real" IP phone, ie voice quality in VoIP-to-VoIP connections is significantly better than that of ISDN. There is finally a real headset connector (cable socket) and ECO DECT for a restful sleep.
From extras like the Outlook synchronization you should not expect too much. Otherwise, I do not want to dwell on the countless functions, but there is a 300-page manual on the manufacturer's website to download, which you should urgently read before handling.
For whom is the DX800A interesting?
For those who want to later or immediately switch to Internet telephony, someday want to use the full IP voice quality, and no mood to have proprietary solutions such as routers with OEM phones. However, one should bear in mind that the other party is also such a great phone needs so that both can benefit from the new audio results.
And ISDN? The old Siemens-Garde apparently still mixed vigorously at Gigaset with and that is a good thing, because no one "understands" ISDN better than the people who have learned it from scratch. However, ISDN is known to be a leaking technology and is currently supported only reluctantly by Telekom for old connections.
How then do you get the DX800A connected to the IP-capable connection of the Telekom?
Import 1. Latest firmware, reset the phone to factory settings.
2. For each MSN own VoIP connection has to be established. Since there is unfortunately only seven compounds can not be used the full 10 MSNs.
3. For the first connection, select the VoIP provider (in this case, T-Online); the device then runs the main parameters of the Gigaset server.
4. Only the following parameters must themselves be registered:
Connection Name or Number: [free text, appears on the display]
Authentication Name / Authentication Name: [do not care, as long as you make a call from the own port. However, the field must be filled with something, a sign is sufficient. No one keeps one's own connection to, here needs the primary email address in, with which one usually checks in with the provider.]
Authentication Password / Authentication Password: [can be left empty, unless you make a call from the own terminal from the other terminal must from here, of course, the correct Anmeldepaßwort pure, which fits to the above email.]
User Name / Username: [This is the outgoing MSN in the international format, starting with +49 ... without 0 for the code]
Displayed Name / Display Name: [does not really matter here, the outgoing MSN pure].
In Speedports or FRITZ! Boxing is - contrary to persistent rumors in various forums - no special port forwarding or even firewall rule needed if a STUN server is configured. This example is the case with T-Online.
Nor must the phone as user "620" or the like. are logged in!
Just a working network jack on the router search, reconnect phone, ready. Disable the upstream router all VoIP or telephony functions.
Conclusion:
With the matching handsets the DX800A is practical telephone system for modern, internetverkabelte family with study at home.
Three individually configurable ABS, many adjustment possibilities make it possible to tailor the phone to many needs. Compatibility with ISDN facilitates the transition to VoIP.
