Each voice response system can have up to four digital trunk adapters physically installed. At a minimum, you must configure at least one trunk. The wizard offers default values for all parameters, so if you are unsure what to do, press Enter to retain the current setting.
Parameters that apply to the whole trunk include line signaling protocol, call direction, outgoing address signaling, incoming address signaling, and area code. The wizard sets these identically for all channels on the trunk. If you need to have channels with different attributes on the same trunk, you can later split the channels on the trunk into two groups. See Defining a channel group using wvrteleconf for more information.
In the trunk specification dialog, you can specify multiple trunks to be configured identically.
