Simple podcast station with phones dialing in - setup problems

I have a Behringer Eurorack UB1204-Pro mixer with several microphones feeding into it. Simply put, all these mics make a combined signal that is fed into the input on the soundcard for my PC, and is recorded for podcasts.

I currently have a Cisco 7961 IP phone that I receive phone calls on, and would like to be able to do two things:
a) Have the audio from the phone go into the sound mixer so that it can be recorded
b) Have the entire signal (minus the dial-in speaker's own voice) fed back to the phone.

I have solved (a) by purchasing a patch logger, a DynaMetric TMP-636, but if i try to use the feedback line on the patch logger, I get terrible echoes. What's worse, my IP phone only let's me log the dial-in caller's voice if I use the actual phone jack, as opposed to the headphone jack, which won't work.


Simply put, does anyone have a solution or an idea which way I should go? I'm tempted at this point to buy a new phone, mixer, and whatever else is needed for a simple setup that would allow dial-in callers and local in-house people using mics to effectively have a simple conference call that can be recorded to PC. Thank you all in advance.

You need a telephone hybrid, as used in pro radio talk-back. The JK doesn't seem too expensive.

They do a few things to get telephone audio into a mixer for broadcast or recording, the main thing being "nulling", which is as per your request to stop the callers own voice being sent back to him, causing a feedback loop.
