Circuit board assistance for a beginner (corded phone hack)?
As it stands the functionality of two buttons is needed - speaker to answer/hang up, and the 9 key to buzz in - but the board itself is larger than the enclosure I had wanted to put it in. Is there a way to get around this? Would it be a matter of having to trace the circuits and physically break off pieces of the board that aren't relevant (keys 1-8, etc), or do I have it all wrong?
Pictured below is the board and the two buttons in question. EDIT: I accidentally circled the key below the 9 key - I'm aware of this mistake.
I am a total newbie when it comes to this stuff so if this is a dumb question I apologize in advance. Additionally, if anyone has alternative solutions or suggestions for this issue I would love to hear them. Thanks!
