Route Name: The name that you will use to identify this outbound route ("local", "international" for example)

Route Caller ID: The 10 digits valid caller ID number, this is the Caller ID that you will pass when you use this specific Outbound route.

This Caller ID will override all the caller ID, except:
*Extension Caller ID (Unless you check the Override Extension when you create the Outbound route).
*Extension Emergency Caller ID (If the Extension and the Outbound route has the Emergency option enabled).
*Trunk Caller ID (In case that you have selected the Force Trunk Caller ID option at Caller ID option in the Trunk settings).

Route Password: In case that you want to ask for a password before the calls connects to the destination.

Route Position: The priority of this route in relation to the other Outbound routes that you have configured.

Dial Patterns: These are a unique set of digits that will active this Outbound Route and will send the Call through the Designated Trunk.

In the case of the Dial Patterns the Elastix PBX has an option called Dial patterns wizards this will allow you to add the Match Patterns
that you will use with this Outbound Route, for this you just have to select, from the drop down menu, the destinations that you would like to call
with this Outbound route  (Local numbers with 10 or 7 digits, Toll-free numbers, International numbers, Emergency numbers, Information numbers, etc) 
and it will automatically add the Match Pattern for those calls.

Additionally we recommend to add a Match Pattern for 4XXX, in order to be able to call to our Echo Test (4443)

Trunk Sequence for Matched Routes: This is the Trunk that your Outbound Route will use to place the calls.

Once you have configured the Outbound Route, click at the Submit Changes button at the end of the page in order to save the settings and then click at the Apply Configuration Changes Here option in red at the top of the page in order to apply the configurations to the PBX system.
