I am not sure if this is the right forum but if anyone could help me it would be much appreciated, i have a samsung phone system that was reinstalled after we got rid of our ip phones by polycom, i installed all the phone back to the original extensions and have dial tone, but the problem is that on line 1 which reads 701 on the button reads 709 on the digital part of the phone, we have 3 lines total, but the buttons on the phone (702) line 2 and (703) line 3 do not light up if pressed until i call my cell phone and press hold starting on line 1 then line 2 then line 3 after doing that the buttons light up and all 3 lines work, i am trying to figure out if it is some programming issues or if is something punched down wrong on the phone system it self. -please help if you can.
