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*)

annex A/B/...

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

other notes

• 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!)
