Trunk Groups
Defines a list of Trunks to consider when making a call. The system will attempt to call out to trunks in the order they are defined, and if each one fails, the call will not be completed. It is important to have your Trunks defined before creating a Trunk Group.
Adding a Trunk Group
1) Enter the CLI's configuration mode.
2) Enter the name of the Trunk Group you wish to create. You will be prompted with the minimum required settings.
vbox-markm(config)# trunk_group main_office
!! Notice: Editing new item: main_office
!! Notice: Minimum requirements needed for insert:
!! desc
!! capacity
vbox-markm(config-trunk-group main_office)# desc "Main Office Trunk Grou"
vbox-markm(config-trunk-group main_office)# capacity 20
vbox-markm(config-trunk-group main_office)#3) Next define the Trunks that the Trunk Group will call out to. We will assume we are using 3 Trunks in this example.
vbox-markm(config-trunk-group main_office)# trunk_pos 1
vbox-markm(config-trunk-group main_office pos-1)# trunk_name ### Use Tab to get a list of available trunks

exit
exit
vbox-markm(config-trunk-group main_office)#4) Next as needed, add additional Trunks to the Trunk Group.
vbox-markm(config-trunk-group main_office)# trunk_pos 2
vbox-markm(config-trunk-group main_office pos-2)# trunk_name

vbox-markm(config-trunk-group main_office pos-3)# exit
vbox-markm(config-trunk-group main_office pos-3)# exit force
vbox-markm(config-trunk-group main_office)#5) Lastly use the show command to ensure your settings have been saved.
