Nortel Networks NN43001-121 manual Parameter Maximum Associations Per DN

Remote Call Control configuration 183

Parameter: Maximum Associations Per DN

This parameter defines the maximum number of simultaneous TR/87 SIP dialogs that can be active for a single DN. Multiple instances of Office Communicator (for example, home, office, laptop) are active and each of them can have its own active TR/87 session. This parameter limits the number of simultaneous client sessions for a single DN.

Parameter: International Calls As National

This parameter is used in combination with the following parameters:

•SIP CTI Dial Plan Prefix - National Prefix

•SIP CTI Dial Plan Prefix - International Prefix

•SIP CTI CLID Parameters - Country Code

When enabled this feature monitors all SIP CTI calls made using the E.164 international number format. For E.164 called numbers that are within the local country the SIP CTI national dial prefix is used to originate the call from the Call Server. For E.164 called numbers that are outside the local country the international dial prefix is used to originate the call from the Call Server.

When this feature is disabled all SIP CTI calls made using the E.164 number format uses the international dial prefix when originating the call from the Call Server.

Two scenarios are provided using the following example parameters:

•SIP CTI Settings - International Calls As National = Enabled

•SIP CTI Dial Plan Prefix - National Prefix = 61

•SIP CTI Dial Plan Prefix - International Prefix = 6011

•SIP CTI CLID Parameters - Country Code - 1

•AC1 = 6

Scenario 1 A call is placed from Office Communicator to +14167008000. The TR/87 Front End application on the Signaling Server uses the above SIP CTI settings to determine that the E.164 destination is within the local country. The call originates through AML from the Call Server using the national dial string 614167008000.

Scenario 2 A call is placed from Office Communicator to +31123456789. The TR/87 Front End application on the Signaling Server uses the preceding SIP CTI settings to determine that the E.164 destination is not within the local country. The call originates through AML from the Call Server using the international dial string 601131123456789.
