Thanks for the replies.

Dave, I hooked up the red line to the relay's common line but no success.

I'm spinning my wheels here and wondering if I should try a different approach. I've been reading a little about interfacing serial modems with PICs and using AT commands to accomplish the off-hook, DTMF/dialing, and on-hook functions. It appears to be an easier approach since all the phone interfacing is taken care of with the modem. I would need to learn the appropriate AT commands (I've come across a few websites that list them) and understand modem-to-PIC connections.

Any thoughts or advice before I pursue this? Thanks.
