TELEPHONE SERVICE PROBLEMS
No Dial Tone
•
Check that the connections to the telephone line and the AC power are
correct and secure.
• Try a different line.
Echoes, Short Silences, or Clipped Speech
• This is normal for the first few seconds of a call as the telephone adjusts to
the room acoustics.

papers on the conference table. Do not touch the phone during a call.
