New page

When working with these PBX-systems, a complete new world has opened.
The possibilities are endless, but there are also some practical limitations.
* The system should work with the already existing PSTN
* The available DECT-telephones must be used.
* Costs should be low.
* Nothing must change for the enduser in order to make a normal call, or to receive one.
* Calling must still be possible when the server or internet is offline.

== Setup with Voice-modem ==
* [http://linuxgazette.net/120/smith.html A $10 Linux Answering machine] - An Asterisk PBX system using an Intel voice-modem.

== Possible problems ==
* Will the connection between the line- and phone-jack be made when the server is offline?
* Is it possible to make the (DECT-)phones ring when someone is calling you via the PBX?
** If not, what is needed (60V power-supply?) to make it work?
