Trouble Hearing Called Party Answer
Possible Cause 1:
If you are using a speakerphone, there may be environmental
factors that affect the performance of the speaker or microphone (for example, too
much background noise).
What to do:
See ‘‘Speakerphone Performance Tips’’ on page 3-8 for suggestions on
the proper use of the speakerphone. If the problem is not solved, go to Possible
Cause 2.
Possible Cause 2:
If the system is set for touch-tone dialing, you may have a faulty
phone or cord. See ‘‘System Phone Does Not Work’’ on page 6-5. If the system is
set for rotary dialing, the Rotary Dialing Timeout interval is too long.
What to do:
Reset the interval using Rotary Dialing Timeout (#108).
If you can hear the called party answer, the problem is solved.
If the problem is not solved, call the hotline (see page 6-1).
Automatically Dialed Calls Beginning with
Star Codes Are Misrouted
Possible Cause:
The Star Code Dial Delay setting is not inserting a long enough
pause, allowing a portion of the phone number to be dialed before the second dial
tone from the Central Office is established.
What to do:
Use Star Code Dial Delay (#410) to increase the Star Code Dial
Delay setting.
Using the Recall Feature Has No Effect
Possible Cause:
Recall Timer Duration setting is too short.
What to do:
Increase the Recall Timer Duration (#107) by 100 milliseconds.
If the Recall feature works, the problem is solved.
If the Recall feature still does not work, continue increasing the Recall
Timer Duration by increments of 100 milliseconds until the problem is
solved.
Using the Recall Feature Disconnects Call
This problem applies when the system is installed behind a PBX or Centrex
system or with the local phone company’s “Call Waiting” feature.
Possible Cause:
Recall Timer Duration setting is too long.
What to do:
Decrease the Recall Timer Duration (#107) by 100 milliseconds.
