Phone Network27VLAN Setting ConfigurationThe following table lists the parameter you can use to configure VLAN setting.Parameter static.network.vlan.vlan_change.enable[1] .cfgDescriptionIt enables or disables the IP phone to obtain VLAN ID using lower preference of VLAN assignment methodor to close the VLAN feature when the IP phone cannot obtain VLAN ID using the current VLAN assign-ment method.The priority of each method is: LLDP/CDP>Manual>DHCP VLAN.PermittedValues0-Disabled1-Enabled, the IP phone will attempt to use the lower priority method when failing to obtain the VLAN IDusing higher priority method. If all the methods are attempted, the phone will disable VLAN feature.Default 0[1]If you change this parameter, the IP phone will reboot to make the change take effect.Real-Time Transport Protocol (RTP) PortsYou can specify the IP phone’s RTP port range. Since the IP phone supports conferencing and multiple RTP streams, itcan use several ports concurrently. The UDP port used for RTP streams is traditionally an even-numbered port. Forexample, the default RTP min port on the IP phones is 11780. The first voice session sends RTP using port 11780. Addi-tional calls would then use ports 11782, 11784, 11786, and so on. The phone is compatible with RFC 1889 - RTP: A Trans-port Protocol for Real-Time Applications - and the updated RFC 3550.TopicRTP Ports ConfigurationRTP Ports ConfigurationThe following table lists the parameters you can use to configure RTP ports.Parameter static.network.port.min_rtpport[1] .cfgDescription It configures the minimum local RTP port.Permitted Val-ues Integer from 1024 to 65535Default 11780Web UI Network->Advanced->Local RTP Port->Min RTP Port (1024~65535)Parameter static.network.port.max_rtpport[1] .cfgDescriptionIt configures the maximum local RTP port.Note: The value of the maximum local RTP port cannot be less than that of the minimum local RTPport.Permitted Val-ues Integer from 1024 to 65535Default 12780Web UI Network->Advanced->Local RTP Port->Max RTP Port (1024~65535)Parameter features.rtp_symmetric.enable[1] .cfg
