Review addressing and name resolution for voice devices

A monthly network review should compare the documented voice path with the active one. Start with a sample device from each distinct site or subnet.

Compare records with live settings

  • Check the subnet, gateway and voice VLAN assigned to the sample device.
  • Compare DHCP option values and lease duration with the approved phone configuration.
  • Resolve the call-server name from the voice network and confirm the intended address family and destination.
  • Review recent route or firewall changes affecting signalling and media.

Record the device, site, time and configuration versions used in the check. Rotate the sample so a successful result on one switch does not stand in for the entire network. Assign a named owner to any mismatch and test again after correction.

Use the IP networking reference for voice deployments for the terms in the record.
