As an example, we will set up a two-way CO trunk group that carries voice and voice-grade data only. Incoming calls terminate to an attendant during business hours and to a night service destination the rest of the time. We’re adding trunk group 5 as an example.
Procedure
Enter add trunk-group next.
In the Group Type field, type co.
This field specifies the kind of trunk group you’re creating.
In the Group Name field, enter Outside calls.
This name will be displayed, along with the group number, for outgoing calls if you set the Outgoing Display field to y. 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 make and 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 field defines a unique code that you or your users can dial to access this trunk group. The code also identifies this trunk group in call detail reports.
In the Direction field, enter two-way.
This field defines the direction of traffic flow on this trunk group.
In the Night Service field, enter 1234.
This field assigns an extension to which calls are routed outside of business hours.
In the Incoming Destination field, enter attd.
This field assigns an extension to which incoming calls are routed during business hours. By entering attd in this field, incoming calls go to the attendant and the system treats the calls as Listed Directory Number calls.
In the Comm Type field, enter voice.
This field defines whether a trunk group can carry voice, data, or both. Analog trunks only carry voice and voice-grade data.
In the Trunk Type field, enter ground-start.
This field tells the system what kind of signaling to use on this trunk group. To prevent glare, Avaya recommends ground start signaling for most two-way CO, FX, and WATS trunk groups.
Press Next Page until you find the Outgoing Dial Type field.
In the Outgoing Dial Type field, enter tone.
This field tells Communication Manager how digits are to be transmitted for outgoing calls. Entering tone actually allows the trunk group to support both dual-tone multifrequency (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 are ready to add trunks to this trunk group. See Adding trunks to a trunk group example.
