Source Line Selection Reference Manual (SIP Version)
Mediatrix 1204 197
• The list is empty. The line selection algorithm cycles through all lines that do not use
source line selection. If no available lines can be found, the call is rejected. See
“Line
Selection Algorithm” on page 198 for details.
Because this variable is located in a table, you can enable/disable the feature on a per-line basis.
Examples of Source Line Selection Use
FXS to FXO Line Mapping
You can map an FXS line of an access device such as the Mediatrix 1104 to a specific FXO line of the
Mediatrix 1204. In this case, a call made from this FXS line will always use the same FXO line. To achieve
that, the Mediatrix 1104 and Mediatrix 1204 configurations would be something similar to the following:
Mediatrix 1104 : IP address 192.168.0.1
sipUAMainUsername = 6661111 (FXS line #1)
sipUAMainUsername = 6662222 (FXS line #2)
sipUAMainUsername = 6663333 (FXS line #3)
sipUAMainUsername = 6664444 (FXS line #4)
Mediatrix 1204: IP address 192.168.0.2
lineSelectionDigitMap (FXO line #1) = 6661111
telephonyAttributesAutomaticCallEnable = enable
telephonyAttributesAutomaticCallTargetAddress = 6661111
lineSelectionDigitMap (FXO line #2) = 6662222
telephonyAttributesAutomaticCallEnable = enable
telephonyAttributesAutomaticCallTargetAddress = 6662222
lineSelectionDigitMap (FXO line #3) = 6663333
telephonyAttributesAutomaticCallEnable = enable
telephonyAttributesAutomaticCallTargetAddress = 6662222
lineSelectionDigitMap (FXO line #4) = 6664444
telephonyAttributesAutomaticCallEnable = enable
telephonyAttributesAutomaticCallTargetAddress = 6662222
With such a configuration, a call made from line #2 of a Mediatrix 1104 is processed on line #2 of the Mediatrix
1204. On the other hand, if a caller from the SCN calls line #3 of the Mediatrix 1204, the call is automatically
redirected to line #3 of the Mediatrix 1104.
Reserving an FXO Line
You can reserve an FXO line for specific individuals. For instance, these individuals could be the management
team members of a company.
If the telephone numbers of the management team are 221 and 222 and you want to reserve an FXO line for
their exclusive use, configure the Mediatrix 1204 as follows:
lineSelectionDigitMap (FXO line #1) = (221|222)
lineSelectionDigitMap (FXO line #2) = xxx
lineSelectionDigitMap (FXO line #3) = xxx
lineSelectionDigitMap (FXO line #4) = xxx
The management team can thus use all FXS lines, while others can only use lines 2,3 and 4.
