PortSIP PBX Must be Able to Join the Multicast Group
In case your network interface does not list this address you are not ready to provision your IP phone via PnP. To resolve it, please follow up below steps:
Open "Control PanelNetwork and InternetNetwork Connections", select the network adapter interface, right click it and choose "properties", select the "Internet Protocol Version 4 (TCP/IP)", click "Properties > Advanced", edit "Default Gateways", and set the "Metric" to 10, then reboot the host. After revalidate if the joins can be seen.
Connect via SSH to the host and switch to “root”. Enter the command “netstat -g” and check if sip.mcast.net is listed for the applicable interfaces.
IP Phone and PBX Must be in the Same Local LAN Subnet
IP Phone Must Support PnP Provisioning
The actual IP phone must also do its part to announce its presence in the network. However, some firmware versions in the past have shown us that this was not operational to its full extent. Therefore, the phone shall, in case it does not work and all aspects above are covered, manually update to the latest supported firmware to ensure PnP functionality.
