Mlx Displays: Private Network Call Display Problems - Avaya MERLIN MAGIX Maintenance And Troubleshooting Manual

Maintenance and Troubleshooting
If changing one or more switch identifiers do not solve the problem, see Possible Cause 2.
Possible Cause 2: More than three analog spans are involved in the call.
What to Do: This may occur when calls are transferred or forwarded multiple times across analog
facilities. Consider changing to digital facilities if this situation occurs frequently. Contact your
Avaya representative or local authorized dealer for instructions.
If the problem is not solved with the above instructions, call the Technical Support Organization at

MLX Displays: Private Network Call Display
Problems
There are several possible causes for this problem, all of them easy to check.
Possible Cause 1: Non-local extension calls and outside calls routed on tandem tie trunks display
at recipient MLX display telephones as outside calls, for example, TIE-TRK .
What to Do: Check the call routing and find out whether any tandem tie trunks are included in the
route. You may need to contact the coordinating system manager. If the call originated from the
PSTN on a PRI or BRI facility with Automatic Number Identification (ANI), the original calling party
information displays when private network routing is over tandem PRI trunks only. Check the call
routing and see whether any tandem tie trunks are included in the route.
Possible Cause 2: Call transferred to the extension.
What to Do: If the call was transferred to the extension, only the transfer originator information
displays, not the name and/or number of the original caller, even if PRI ANI was available for the
original call.
Possible Cause 3: Display Preference setting for MLX incorrect
What to Do: If the call route for an intersystem call includes only tandem PRI trunks and the call
was not transferred, the Display Preference setting for the MLX display telephone extension may
not be programmed as you expect. The factory setting displays the caller's extension number.
Check System Planning Form, MLX Telephones, for the recipient extension or see "Display
Preferences for Intersystem Calls" in Chapter 5 of Network Reference to check the setting through
system programming. If you see the word "Ext" in the display, change the programming to Both.
You can see a report for the extension, showing the display preference, by choosing the Print
option on the System Programming menu, then selecting Ext Info and entering the extension
number. If the display shows a 10-digit ANI as PRI-TRK Ext 9089575555 , you may want to
change the display option from Name to Both and then the display would look like PRI-TRK
9089575555 .
