Phone Model: SPA504G
When receiving an incoming call, the phone rings and the open line light flashes green. When I pick up the phone handset, the active line light turns red for a few seconds, then goes out. I don't hear anything, nor can the incoming caller hear me, until I press the active line button only after the red light has gone out after picking up the handset and waiting a few seconds.
Similarly, if the phone rings and I pick up the handset and press the active line button immediately after picking up, I then need to press that same line button 2 or 3 more times to be able to speak to/hear the caller. (Only way I can visualize it is opening the line too early, then closing it, then opening it again).
What is wrong with either the network connection or phone settings that may cause the phone not to answer immediately when I simply pick up the handset?
Thank you very much for your help.
