Mute speaker on M7310 - NorStar Meridian M7310 Phone

I've had Nortel Norstar m7310 phones for years and the entire time that I've them, I've never used the speaker phone. I could hear them, they couldn't hear me. At this site, I figured out how to fix that and now the speaker phone works. It created another problem. For me to use the Called ID, I would have to press the line that was calling and I would see who it was that was calling. Now, when I do that, it immediately picks up the phone versus letting see who is calling. I want to be able to both see who is calling and use the speaker phone. Thanks.
