IP8000 Conference Phone Application Note—Page 6
The next item on this screen is the “Enable Digest Authentication” eld. This is a SIP feature that allows a user ID and
password to be established for authentication. If this feature is congured for the Trunk Group the same settings must be
congured on the IP8000 although it is not necessary to enable this functionality for the IP8000 to operate properly.
The “Enable SIP Info for G.711 DTMF Signaling” box should not be enabled. Enabling SIP info is currently only used with SIP
tie trunks between ShoreTel systems.
Figure 10 – Inbound Trunk Settings
For the Inbound Trunk Settings, ensure the “Number of
Digits from CO” matches your current extension length. It is
not necessary to select the “DNIS” (Dialed Number Identi-
cation Service) box to create a DNIS to extension mapping
or the “DID” (Direct Inward Dial) box to input a DID range.
You must enable the “Extension” parameter, this will allow
incoming calls to be directed to the extension dialed. It is
not necessary to utilize a “Translation Table”, unless you
plan on modifying the incoming digits. The last step for the
Inbound Trunk conguration is to enable the “Tandem
Trunking” parameter to allow trunking between trunk
groups. The “Destination:” should be congured for the
desired extension that a call should be routed in the event
that a user misdials a number, the example above (gure 10)
has an Auto Attendant congured. Trunk calls not routed by
previous entries under the Inbound Trunk routing will be
routed to the congured extension or as in Figure 10 to the
Auto Attendant.
