Can not get a dial tone on my new phone - Lands Phones

At an educated guess sounds like dial tone is set to decadic if there are two phones the other phone will set off ringer when numbers dialed. May need to get phone provider to change dial mode in exchange line interface circuit to be Dual tone Multi Frequency Dialing and then switch phones to Tone dialing rather than pulse dialing.

Is the base station plugged into the phone jack on the wall?

Check the side of the phone. Look for TONE / PULSE selection.

MOVE it back and forth and leave it to TONE.

Test it again,

Resetting the voice message waiting indicator
When you receive a new voice mail message, the new message LED on the top of the handset flashes. In the event your message waiting light gets out of sync with your phone company's
voice messaging system, you can manually reset it back to the "No messages waiting" state.
1. Press and hold FiND on the base for five seconds.
Note: The handsets connected to the base will start to beep, however, keep pressing for five seconds.
2. A beep sounds and the message alert tone is reset.
Changing the dial mode
Your phone can communicate with the telephone network in two different ways: tone dialing or pulse dialing. These days, most base networks use a method called tone dialing, so your phone comes programmed for tone dialing. If your phone company uses pulse dialing, you will need to change your phone's dial mode. If you don't get a dial tone or can't connect to the telephone network, please follow the steps below to modify your phone's settings:
1. Press MENU/SELECT.
2. Select the Global Setup menu, and then the Dial Mode submenu.
3. Scroll to highlight Pulse.
4. Press MENU/SELECT. You will hear a confirmation tone.
If you ever need to change the dial mode back to tone dialing, follow the same procedure, but select Tone in step 3.

Finally for future ease of use, here is a link to the user manual were I copied the above information from:

Here's what the manual says: Changing the Dial Mode (Tone or Pulse Dialing) (HS1 only) Your phone can communicate with the telephone network in two different ways: tone dialing or pulse dialing. These days, most phone networks use a method called tone dialing, so your phone comes programmed for tone dialing. If your phone company uses pulse dialing, you need to change your phone's dial mode. If you don't get a dial tone or can't connect to the telephone network, follow the steps below to modify your phone?s settings: With the phone in standby, press and hold [cid/menu]. Press [vol/ / ] to move the pointer to select DIAL. Press [select/channel] to set the phone to pulse dialing. Press [end]. Return the handset to the base. The handset communicates the new setting to the base, and the base activates the setting on any other handsets. Hope this helps out. K

That isn't a whole lot to work with. Get a working phone and take the cord out of the base of the GE and plug it into the working phone.
If the working phone gets a dial tone, look into the modular receptical on the GE base and see if the contact wires aren't out of place.
If you don't get a dial tone on the working phone, try changing the connection cord between the phone and the wall. Also look for the same problem in the wall receptical as discribed above for the GE base.

Purchase another unexpensive phone. Check if you have dial tone. If not call your carrier.

All you have to do is put the phone that does not get a dial tone on the MAIN CHARGING BASE for 20 seconds! it will then sync up!

Good luck!

Lisa, If the 900MHZ phone is Model 26928M programming for rotary dial usually goes like below, can't hurt to try on any model. TONE/PULSE DIALING This adjustment allows you to select tone (touch-tone) or pulse (rotary) mode dialing. The phone is pre-set for touch-tone use. To set to tone or pulse dialing: 1. Press and hold the program button for two seconds. You will hear a beep. 2. Press the *tone button to select Tone Dialing or press #pause to select Pulse Dialing. 3. Press the program button again. You will hear a confirmation tone.
