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 Lucent Technologies representative or Local
Authorized Dealer for instructions.
If the problem is not solved with the above instructions, call the Lucent
Technologies Helpline at 1 800 628-2888; consultation charges may apply.
MLX Displays: Network
Call Display Problems 6
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,
7,(75.
.
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” on page 31 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
3ULQW option on the System Programming menu, then selecting
([W
,QIR
and entering the extension number. If the display shows a 10-digit ANI as
35,75.([W, you may want to change the display option from
Name to Both and then the display would look like 35,75.
