The system assigns the next available trunk group number to this group. In our example, we’re adding trunk group 5.
In the Group Type field, enter did.
This field specifies the kind of trunk group you’re creating.
In the Group Name field, enter Incoming calls.
You can type any name up to 27 characters long in this field.
In the COR field, enter 85.
This field controls which users can receive calls over this trunk group. Assign a class of restriction that’s appropriate for the COR calling permissions administered on your system.
In the TAC field, enter 105.
This code identifies the trunk group on CDR reports.
In the Trunk Type field, type wink-start.
This field tells the system what kind of signaling to use on this trunk group. In most situations, use wink start for DID trunks to minimize the chance of losing any of the incoming digit string.
In the Incoming Dial Type field, enter tone.
This field tells Communication Manager how digits are transmitted for incoming calls. Entering tone actually allows the trunk group to support both DTMF and rotary signals, so Avaya recommends that you always put tone in this field.
In the Trunk Termination field, enter rc.
Use rc in this field when the distance to the central office or the server at the other end of the trunk is more than 3,000 feet. If you do not know the distance to your central office, check with your service provider.
Select Enter to save your changes.
Now you’re ready to add trunks to this trunk group. See Adding trunks to a trunk group example.
See Digit insertion and absorption with trunk groups for instructions on matching modifying incoming digit strings to match your dial plan.
