Telephone Does Not Ring
• Make sure the Do Not Disturb (DND) feature is not activated.
• Make sure ringers are turned on.
• If there are several non-system phones on the line that don’t ring,
disconnect some of them. Having too many phones connected can
also result in low ringer volume for non-system telephones.
• If the INTERCOM light flashes but you don’t hear a paging signal,
make sure the Do Not Disturb feature is not activated.
Intercom Paging Signal Not Received
Make sure you have programmed your intercom extension number
correctly. Line 1 must be connected at all extensions, and must be the
same telephone number/line for Page and Intercom to work properly.
Cannot Join a Conversation in Progress
The privacy feature prevents another set on the system from interrupting
a conversation. Make sure you press the LINE button to release privacy.
Error Tone (Fast Busy Signal) Heard When Making an Intercom Call
The Do Not Disturb feature is activated at the extension you are calling.
Line Lights Remain On When No Line is Connected
• Make sure the phone is programmed for that line to be absent.
(See “Set Line Usage for Each Line”in FEATURE SET UP.)
• Make sure that your Line Groups are programmed properly.
(See “Assign the Line Group for this Phone”in FEATURE SET UP.)
• Disconnect all other devices (fax,modem, credit card reader, etc.)
from any lines connected to your 944 phone. These devices can
interfere with the telephone’s data links.
• Make sure the total length of telephone wiring used in your phone
system is less than 600 feet. If the wiring is longer, you may need to
use a special filter device. Call 1 800 222-3111 for information about
this filter. You’ll need to contact a professional to install this filter.
