Incoming call configuration
To receive an incoming call directly to the telephone from a VoIP network, you need to ensure that
the telephone is mapped to a target line
For information about setting up your Business Communications Manager to place outgoing VoIP
calls, see “Outgoing call configuration” on page 63.
Assign a target line to the DN
A target line routes incoming calls to specific telephones (DNs) depending on the incoming digits.
This process is independent of the trunk over which the call comes in.
Other options:
• You can assign the target line to a number of telephones, if you want the call to be answerable
to a call group, for instance.
• If System-Wide Call Appearance (SWCA) keys are configured on memory buttons on the
telephones, the incoming line acts the same way as any other incoming call, which depends on
how SWCA has been set up to behave. Refer to the Business Communications Manager 2.5
Programming Operations Guide and the Telephone Feature Programming Guide for more
information about setting up SWCA keys.
• You can assign the target line number to a Hunt Group DN if you want the call to appear on a
group of telephones set up as a hunt group. Refer to the Business Communications Manager
2.5 Programming Operations Guide and the Telephone Feature Programming Guide for more
information about setting up Hunt groups.
Mapping target lines involves two steps:
• The target line is mapped to a telephone (or Hunt group) by assigning the line (241) to the
telephone (or Hunt group) DN record.
• The incoming digits (e.g. 3321) are mapped to a target line (e.g. 241) by setting the Received
Number under that target line to the incoming digits.
If your system does not have target lines already assigned, use this procedure to assign target lines
to individual telephones.
1 In Unified Manager, open Services, Telephony Services, System DNs.
2 Under the Active Set DNs (or under the Inactive DNs, if you are preconfiguring DN records)
choose the DN record of the telephone where you want the line to be directed.
3 Choose Line Access, Line assignment and click the Add button.
Note: You can also use the Add Users wizard if you need to create target lines for a range
of telephones. Refer to the Business Communications Manager 2.5 Programming
Operations Guide for detailed information about using the wizard.
