Hello- what I was thinking of doing was connecting an analog speakerphone to the headset or handset jack of the cisco phone so we can have better quality conference calls. Can this be done?

Thank you for your help

Probably by attaching it through the handset cable using an adaptor like JK Audio ( Be aware that you may introduce echo problems by doing this and it has to be powered externally.

Also not sure what IP phone model you have, but the 7970 has External speaker and microphone ports:

Hope this helps & Have a nice day!
