82 Matrix ETERNITY NE System Manual
Select Trunks for Outgoing Calls
Outgoing calls (to external numbers) are made by dialing Trunk Access Codes (TAC).
• TAC for users worldwide are: 0, 5, 61, 62, 63, 64.
• TAC for users in USA are: 9, 5, 81, 82, 83, 84.
For each TAC, you need to select the Outgoing Trunks. All external calls made by dialing a particular TAC will be
routed through the outgoing trunks you selected for that TAC.
You can also apply Least Cost Routing logic on the selected trunks, so that ETERNITY will route the outgoing call
through the trunk that costs the lowest for the call.
1. Click (+) to expand Select Outgoing Trunks options.
2. Select Trunks allowed for ‘0’ dialing. The outgoing call will be routed through the selected trunks when
the extension user dials TAC ‘0’.
• Double-click the field. A multiple selection box opens.
On the left, the trunks appear with their names (if configured in “Naming Trunks”) and port numbers in a
sequence, starting with CO trunks, followed by Mobile trunks and SIP trunks.
If you have not assigned any names to the trunks, they will appear with their default names (CO, MOB,
SIP) and port numbers.
If you have enabled On-Site Configuration, only those trunks that are connected will appear in the box.
• To select a trunk, place your cursor on the desired trunk, and click the Select>> button.
Or
• Press the ctrl key and click the left mouse button to select multiple trunks.
• You may change the sequence of the trunks you selected, if required, using the Up and Down arrow
buttons on the right display box.
• You can also delete trunks from the ones you have selected.
• You may enable Rotation, if you have selected more than one trunk. Default: Disabled.
When you enable Rotation, each new outgoing call is routed through the subsequent trunk in the
group
16
. This ensures equal distribution of outgoing call traffic on all trunks.
16. The first call through the first trunk, the second through the second, the third through the third trunk, and so forth. Thus each new
call is routed through the trunk next to the one that routed the previous outgoing call.
