After you have created the new signaling group and trunk group for messaging, you must modify the signaling group to associate it with the new trunk group.
Procedure
At the SAT interface prompt, enter change signaling-group<nnn>, where <nnn> represents the number of the signaling group you created while creating a signaling group for messaging.
The system displays the signaling-group window.
Set the Trunk Group for NCA TSC field to the number of the new trunk group.
For example, if you created the new signaling group and the new trunk group as 99, enter 99 in this field.
Set the Trunk Group for Channel Selection field to the number of the new trunk group.
For example, if you created the new signaling group and the new trunk group as 99, enter 99 in this field.
Press the key combination Control E to save the values set in the window.
