Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having connecting your phones.
To help you with this issue, I'm going to need a bit more information, such as:1) The FULL Make & Model Number of the phone system(s) you are working with? If cordless system(s), that model should be printed on a sticker on the bottom or back of the main base unit of each system.
2) How many TOTAL cordless handsets do you have with each system?
3) What phone service provider (phone company) you have for this phone line?
4) How many phone jacks to you have available - that are part of this same phone line?
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)
