Some information on tested Fritz!Boxes.
For a list of devices with their specs, check the wikipedia page
|Fon WLAN 7270||yes|
|Fon WLAN 7340||no(?)*|
|Fon WLAN 7360||untested(?)*|
*) Responds to dialing 999 by calling all extensions connected.
recover SIP settings
Copied from blog.lix.cc:
- enable telnet by calling #96*7* (you can use "Click to dial" in the webinterface)
- telnet to your box's IP (alternatively, you could use fritz.box or 169.254.1.1)
- export the VoIP part of the config
allcfgconv -C voip -o /var/tmp/temp -c
- display the contents (filter by "password")
cat /var/tmp/temp |grep passwd
- disable telnet (#96*8*)
I think typically Dutch consumer DSL is annex A (POTS). See the wikipedia page on G.992.3.
- A: POTS: upstream starts at 25kHz
- B: ISDN: upstream starts at 138kHz
- set DTMF transmission to "RTP or in-band" if FreeSWITCH doesn't respond to the input, and displays the following message on the console:
IGNORE INFO DTMF(4) (This channel was not configured to use INFO DTMF!)
connecting the Fritz!Box
- Note that the Fritz!Box is pretty quirky regarding SIP: it can't handle a 407-unauthorized correctly when in router mode (which is needed to differentiate between public and internal calls). xopr had more success setting the device as a flat switch and putting it behind a generic router (tested with a ZyXel).
- It also doesn't like usernames; you have to start with a number and change it afterwards.
- It does seem to have more ring power than the tested ZyXel, though.
