Phone System: Unterschied zwischen den Versionen

Version vom 20. April 2012, 23:49 Uhr

The current phone system consists of one Fritz!Box 7170 and a Fritz!Fon 7150. The 7170 is used as a ISDN/Dect converter and hosts a Registrar for SIP accounts. The 7150 and the VP5500 in the Basement are connected to the 7170 via Ethernet:

-- UK0 -- NTBA -- ISDN S0 -- Fritz!Box 7170 -- SIP --> DECT (Base 1) --> DECT Handsets
                                    |
                                     `-- SIP --> WLan / Voip Phone

Cells & Range

Base station number 1 is located in the lecture room, providing telephony via DECT to almost the entire Labor. 2 Handsets situated in lounge and lecture room are registered to that base station.

VOIP service

As mentioned above, the boxes are connected to one another via SIP. Incoming calls on the ISDN line are converted to SIP and then signalled to all connected clients (thus the 7150 and VP5500).

Planned Services / TODO

Assign fixed numbers to handsets
Port the Asterisk-phone-reminder to dtmfbox
external VOIP connectivity (if internal resources allow)

-The current phone system uses two Fritz Fon 7150 Boxes, one of them is directly connected to the external ISDN bus, the other one is connected to it via ethernet. The ethernet connection is used to forward VOIP calls from one station to the other.
+The current phone system consists of one [http://www.wehavemorefun.de/fritzbox/index.php/7170 Fritz!Box 7170] and a [http://www.wehavemorefun.de/fritzbox/index.php/7150 Fritz!Fon 7150]. The 7170 is used as a ISDN/Dect converter and hosts a Registrar for SIP accounts. The 7150 and the [[VP5500]] in the Basement are connected to the 7170 via Ethernet:

-Due to the nature of the S0 bus, calls may not be transferred from one device to another without occupying the bus (thus blocking it for incoming calls).
-For this reason, one of the base stations is linked to the other one via ethernet. Base number 1 hosts a SIP server (dtmfbox), while the other Box registers to it - this way the amount of internal and/or conference calls is no longer limited by the capabilites of the ISDN S0 bus, but by the capabilities of the DECT base station (which supports 2 voice channels at a time).
 == Cells & Range ==
-Base station number 1 is located in the basement, serving the basement and lecture room, while base station number 2 is standing on the table in the lounge and serves as base station for the workshop. The handsets from the good old Gigaset are registered to both base stations and will automatically choose the best one, but they don't support taking a call from one cell to another. All other handsets are registered to a fixed base station.
