Turns on but no dial tone - Nortel MERIDIAN M2250 ATTENDANT CONSOLE (NT6G00-35-003)

Try this

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.

Try:
Turn off power for the base.
Turn off phone and take out batteries.
Wait few seconds then put batteries back.
Will help if you unplug and plug the cables.

To set Unconditional Call Forward ON Dial "*72" for a dial tone. Dial the forwarding number followed by "#". Wait for dial tone. LCD will display "Call FWD Activated"
To Cancel Unconditional Call Forward: dial "*73" and get the dial tone, then hang up. LCD will display "Call FWD Activated

but, since you have tried those two, it could be that there might still be a different type of call forward option that is still ON, on your phone like Busy Call Forward and Delayed Call Forward 1. To Cancel Busy Call Forward: dial "*91". Wait for dial tone. Hang up.
2.To Cancel Delayed Call Forward: Dial "*93" for a dial tone, then hang up.

Disconnect the telephone-cable from the computer's modem.
Does your telephone regain the dial-tone?

If so, then replace the computer's modem -- it is going "off-hook" as soon as you turn on the computer, not just when you try to use the modem to open a dial-up session.

I would contact your phone provider. It could be a coinceidence that the dial tone stopped working.
DSL does not require dial tone to work.

First thing is to ensure that you have dial tone by picking up the handset on the fax machine and listening for dial tone.If there is no handset take a standard house phone and plug it into the jack where the fax machine was inserted. If there is dial tone on the phone then I would advise you to turn the power off the fax for two minutes then power back on. If there is no dial tone on the phone line contact your vendor or local phone carrier and report NO DIAL TONE

The Vetech phone will only support tone dialing. It does have a menu option that turns tone on or off but it still will not allow pulse dialing. I had to change the phone service from pulse dialing to tone dialing to get the phones to work. As it turned out, the phone company no longer charges extra for the tone service.

Dear

Please go to tone setting & turn off key pad tone

Thanks
