Tone dialing allows your telephone to communicate with devices and services that respond to tone signals, such as answering machines, fax, or automatic switchboards. Want to learn how to switch from pulse to tone dialing on the Nortel phone? Follow these simple steps.

While on an active line, or after selecting the line, press # and the phone will switch from pulse to tone dialing. After you hang up the phone, your phone will return to pulse dialing. You may repeat these steps as needed.

You need to set your phone to emit tone sounds when dialing instead of the clicks. It is a setting in your phone's personal settings.

Maybe your line is out of service, you can test it by connecting a standard wired phone to the line cord instead of your wireless phone base, if you have dial tone, the problem is at your wireless phone system, if there's no dial tone it could be a cable failure or in the central office, in this case you have to report it to the corresponding phone company.

Since you declined to specify the model of your Uniden cordless phone, I can only suggest you select it from the list beginning here to download a copy of the manual. The manual will explain how to switch between tone and pulse dialing.

place that headset in the BASE not one of the stand alone chargers for a few seconds. that should "sync" it with the system.

Hi,

Have you set up 'Call Divert' which returns a 'Broken Dial Tone'

Dial #21# if it is on a Single Line Telephone, or if fitted on a Business System check programme for 'Call Forward'

they are either restricted or what you are hearing is intercom tone and not dial tone. the phones may be set to dial out from a diffrent line grop as well have you tried dialing 81 82 instead of 9 and see what happens

put the phone to your ear and press any digit---you should hear a short burst of tone--if not you may be analogue pulsing which takes forever wait wait wait or change your phone to send tones instead.do this or check this in the menu for whatever kind of phone you are using....i hope this helps

Replace the Power supply

Press * tone button for tone or # pause for pulse selection. 4. Press the program button again. You will hear a confirmation tone.
