Chapter 3 Configuring the Cisco IPVC 3500 Series Gateway
Configuring Gateway Settings
Deleting ISDN Information Elements
In the Advanced ISDN section of the PRI Port tabs, you can delete an ISDN information element.
Procedure
Step 1
In the Gateway interface, on the sidebar, click Gateway (if not already selected).
Step 2
Click the applicable PRI Port tab.
Step 3
Click the Advanced ISDN button.
Step 4 Select an ISDN information element and click Delete .
Configuring BRI or PRI Port Call Policies
In the Call Policies section of the BRI Port or PRI Port tabs, you can configure the incoming call routing
methods available in the gateway for each specified port. You can define each BRI or PRI port with
different settings.
Procedure
Step 1
In the Gateway interface, on the sidebar, click Gateway (if not already selected).
Step 2 Click the applicable BRI Port or PRI Port tab.
Step 3
Click the Call Policies button.
Step 4 Select the Same as Port check box to duplicate call policies settings from another BRI or PRI port that
you choose from the field. When selected, you cannot modify any settings in this section. This option is
unavailable in gateways that support only one BRI or PRI port.
Step 5
In the Enable inbound routing methods section, you can select incoming call routing methods in the
following order of priority:
• DID —When selected, enables Direct Inward Dialing to an endpoint.
•
TCS4 —When selected, enables TCS4 dialing. This setting does not apply to voice calls.
• IVR —When selected, enables the Interactive Voice Response operator.
•
Default extension —When selected, enables the use of the default extension number that you enter
in the field.
Step 6 Select the Overlap Receiving check box to enable overlap receiving functionality. In this functionality,
the gateway can receive consecutive digits until the dialing is complete, instead of receiving the entire
phone number as a block of digits. The gateway recognizes that an overlap receiving dialing is completed
when it receives a fixed, predefined, incoming number of digits. If the gateway receives a complete
indication notification from the switch (PSTN) or a timeout before all the digits have been dialed, the
call might connect to a different address or rejected. If you select this setting, perform step 7, otherwise
skip to step 8.
Step 7
In the Incoming number of digits field, enter the number of digits you want the gateway to expect
during overlap receiving. The gateway waits until this number of specified digits is received and then
processes the whole number. You can enter any value up to 32.
