Hello & Welcome,
I'm Greg and will be assisting you today.
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 AGE of this system?
2) How many TOTAL cordless handsets do you have with this system, and if more than one, do ALL handsets have the "line in use" on the display?
3) What phone service provider (phone company) you have for this phone line?
4) If you have ANY other devices - NOT part of the Vtech system - attached to this same phone line and if so, are they working properly?
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)
