Troubleshooting
IBM CTS Installation Guide 50
•
Remove the RJ-21X cable and measure the voltage between the tip and ring.
If the voltage difference is less than 40 volts, contact the telephone company
to have them correct the problem.
•
When IBM Telephony server is powered down, line X1 and trunk 1 will still
be available. If they are not, your phone wiring may be at fault.
No audio while on hold
•
Connect headphones to the audio cable to make sure that there is audio
playing
•
Make sure that you have selected audio in your system configuration.
Your new auto attendant recording doesn’t play
•
ATTEND.MU is the correct file name for the auto attendant message.
•
If you recorded a new message, make sure that you have copied the file
RECORD.MU to ATTEND.MU in IBMCT/AUDIO.
Unexpected results from calling operations
•
Verify which translation table information has been written to the IBM-
CT618 board.
•
Make sure that the translation table entries are correct. IBM Telephony does
not validate the information entered in the translation table.
Using Flash button to place call on hold hangs up call
•
Flash interval may need to be increased for your model of handset. Refer to
the Administration Guide for information.
Speaker phone not functioning
•
Some speakerphones do not operate properly with IBM CTS if used without
batteries or an external power source, since they draw more current than the
CT-618 can supply.
