If you can nail it on the network side it's easy. Ethereal will record and 
even graph different protocols for you. 

On the phone side one there are specific tools but they cost usually a lot of 
money. (Starting over $10K.) If it's coming in over a serial port one can rig 
something to listen and record that, but you'll probably need to be handy 
with a breakout box. (In effect it opens up the serial cable so you can 
configure it the way you want to.)

I could not give you how to do that without just figuring out and doing it 
myself and I'm afraid I don't have that kind of time.
