  • Call forwarding
  • 5 Meeting rooms that are reachable via PSTN and SIP. These have an optional PIN code, which can be set by the first participant.
  • 4 public PSTN numbers that are hard wired to 4 specific SIP accounts, which end up being part of our 4 conference numbers on the SURFnet MCU
  • Call recording via *1, this puts WAV files in a web accessible directory
  • Remote pickup (*42)

Proposed set-up

We would like to get rid of the server and go for a hosted solution. This would then allow us to get rid of the 4 KPN ISDN lines.
Since we actively use IPv6, any hosted solution should ideally be accessible via IPv6.
The SwissVoice phones should be replaced by something new and better. Since we have good experience with SNOM, this might be good option?
SNOM also has IPv6 support, and they seem to have all the devices that we need: fixed phones, DECT phones, conference phones.
