Hi, I can help DO you have the user manual for your phone?
Or did you need an online copy free?
One you can save and print out if you like. Or you can just read through it page by page as you are setting all that up.
Hi here is the link for the manual.
Please go through the set up and reset your phone system to be sure everything is ok as well.
Also let me know if you were able to get the message set;-)
Please see: http://phone.manualsonline.com/manuals/mfg/panasonic/kxtgea20.html
In any case, I will stick with you until this is complete.
Please rate my service kindly.
Also it is the only way I am credited for my time and expertise with you.

Then you can reach me by simply replying to this message anytime.
Thank you and have a great day!
