The phone system

Individual Phone Setup

  • VLAN 60
  • Statically assigned in 10.28.8.x range (255.255.255.0 netmask)
  • DNS is 8.8.8.8 and 8.8.4.4
  • Default Gateway 10.28.8.254 (a separate VLAN on main Internet connection)
  • sip to sip.gradwell.net, outbound proxy nat.gradwell.net:5082
  • SIP port must be unique for each phone
  • IP and SIP port historically random. Recommendations going forward:
    • End part of IP is extension number minus 300 (e.g. ext 324 has IP 10.28.8.24) except for the reception phones which should use 10.28.8.200 and 10.28.8.201.
    • SIP port is extension number plus 5000 (e.g. ext 324 has SIP port 5324)

We have had a situation in the past where DNS for voip.northarbour.com was down and was preventing us from accessing the web based configuration utility. If this happens in future we can spoof up an IP address for voip.northarbour.com to point at 79.135.123.120.
