Trunking technology is complex. Following a process can prevent mistakes and save you time. Avaya recommends following the process below (some steps might not apply to your situation) to set up new trunks and trunk groups,:
Procedure
Install the necessary circuit packs and perform any administration the circuit pack requires.
Connect the appropriate ports to your network service provider’s trunks.
Administer a trunk group to control the operation of the trunks.
Assign the ports you’re using to the trunk group.
For outgoing or 2-way trunks, administer Automatic Route Selection so Communication Manager knows which outgoing calls to route over this trunk group.
Test your new trunk group by placing a variety of call using the trunk access code.
Using the trunk access code, place a variety of calls.
See Modifying Call Routing for detailed information on Automatic Route Selection.
