DESCRIPTION
Specify the service type for this BRI trunk.
Select DDI/DID (Direct Dialing In) when you want people to use a "direct number"
to dial an outgoing call. You can also specify a prefix number in the caller number
that might be required by your telephone company for outgoing calls using DDI/
DID. See DDI (Direct Dial In) on page 205
Select AA (Auto-Attendant) for all calls coming through this interface will be
switched to the Auto-Attendant system first. See
more information.
Select Direct for all calls coming through this interface and from trusted callers will
be forwarded to extensions. See
more information.
Select MSN (Multiple Subscribe Number) for all the calls to MSNs coming through
this interface will be switched to the Auto-Attendant system first. See
Multiple ISDN Numbers on page 204
Select the type for the prefix number which might be required by your telephone
company to make outgoing calls. The options you can select are UNKNOWN,
INTERNATIONAL, NATIONAL, NETWORK, SUBSCRIBER, ABBREVIATED.
Enter a number to add in the beginning of the outgoing caller's numbers using this
trunk line.
Enter your ISDN number registered to your telephone company. This number is
used for the caller number when you make an outgoing call through the trunk from
the extension which cannot be found in the DDI mapping table.
This column displays the available slots and ports on the X6004. Click one slot
and port and then click the Right icon if you want to add it to this outbound group.
This column displays the ports currently configured for this outbound line group.
Click one port and click the Left icon if you want to remove it from the outbound
group.
If you configure more than one interfaces in this outbound line group, the X6004
check and pick one of them available for an outgoing call.
Use this section to configure your DDI mapping table.
Enter a number (1~20) to identify the extension mapping digits from right to left, so
a DDI mask of 2 applied to the incoming ISDN number 555-123456 would identify
the numbers 56.
Enter the DDI number (like the example 56 above) and its associated extension
number (for example, 6012).
Click this to add a DDI mapping rule.
Click this to delete a DDI mapping rule.
The settings in this section are optional. Leave them empty to allow all incoming
calls. Alternatively, you can define trusted caller number(s) to filter incoming
callers. Then the X6004 only forwards the calls that their caller numbers are listed
in the trusted caller table.
Enter a number (1~20) to identify the phone number length for trusted callers.
Enter a phone number you accept the caller to dial extensions using this outbound
group. Click the Add icon to add a number into the trusted caller table. Click the
Delete icon to remove a number.
Click this to save your changes.
