Trunk Groups

Defines a list of ~~Trunk~~Trunkss to consider ~~for~~when making a call. The system will attempt ~~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)#

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 ~~too.~~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)1)# trunk_name          ### Use Tab to get a list of available trunks
AudioCodesFXO1    branch-iax        isoft-sr-in-2     pbx-sip-t1-gw2    building_a        isoft             pbx-sip-t1-gw1    isoft-sr-out-1    Nathan_Test_Trunk isoft-vit-out-1   isoft-sr-in-1
trunk-bob
vbox-markm(config-trunk-group main_office pos-1)1)# trunk_name building_a
vbox-markm(config-trunk-group main_office pos-1)1)# exit                ### Returns to main config options for the trunk group
vbox-markm(config-trunk-group main_office pos-1)1)# exit force
vbox-markm(config-trunk-group main_office)# show
! Generating running-config
!!!
 

! -------------- Trunk Groups ----------------
trunk_group main_office
  callerid passthrough
  capacity 20
  desc "Main Office Trunk Grou"
  record inherit
  trunk_pos 1                       ### This trunk group has been successfully added as position 1
    trunk_name building_a
exit
  exit
exit
 
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)2)# trunk_name
AudioCodesFXO1    branch-iax        isoft-sr-in-2     pbx-sip-t1-gw2    building_a        isoft             pbx-sip-t1-gw1    isoft-sr-out-1    Nathan_Test_Trunk isoft-vit-out-1   isoft-sr-in-1
trunk-bob
vbox-markm(config-trunk-group main_office pos-2)2)# trunk_name isoft
vbox-markm(config-trunk-group main_office pos-2)2)# exit
vbox-markm(config-trunk-group main_office pos-2)2)# exit force
vbox-markm(config-trunk-group main_office)# trunk_pos 3
vbox-markm(config-trunk-group main_office pos-3)3)# trunk_name
AudioCodesFXO1    branch-iax        isoft-sr-in-2     pbx-sip-t1-gw2    building_a        isoft             pbx-sip-t1-gw1    isoft-sr-out-1    Nathan_Test_Trunk isoft-vit-out-1   isoft-sr-in-1
trunk-bob
vbox-markm(config-trunk-group main_office pos-3)3)# trunk_name Nathan_Test_Trunk
vbox-markm(config-trunk-group main_office pos-3)3)# exit
vbox-markm(config-trunk-group main_office pos-3)3)# exit force
vbox-markm(config-trunk-group main_office)#

5) Lastly use the show command to ensure your settings have been saved.

vbox-markm(config-trunk-group main_office)# show
! Generating running-config
!!!

trunk_group main_office
  callerid passthrough

    trunk_name building_a
exit
  exit

  trunk_pos 2
    trunk_name isoft
exit
  exit

  trunk_pos 3
    trunk_name Nathan_Test_Trunk
exit
  exit
exit
