Hello & Welcome,
Sorry I didn't see your question earlier and to hear of any issue you are having with your phones.
To help you with this issue, may I ask:
1) The FULL Model Number of the phone system you are working with? If this is a cordless system, that model should be printed on a sticker on the bottom or back of the main base unit and START with KX-TGE, but NOT have an "A" in it. EXAMPLE: KX-TGE123.
2) What phone service provider (phone company) you have for this phone line?
3) Can you do a quick TEST for me? That TEST is to pick up any handset, press the TALK button, and QUICKLY listen for the dial tone and let me know what you hear.
Let me know if you hear a CLEAR STEADY dial tone, or perhaps a few "beeps" or "pulsed" dial tones, followed by a steady dial tone.
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
