I have worked with TP560 modems before (somewhat indirectly), but I do 
not have a MultiTech modem with a TP560 chipset... in fact, I did not 
know that MultiTech even made a modem with the chipset.

That's not uncommon, sadly.

I don't know of any consumer-grade full duplex voice modem.  I looked 
for them for a while.  If you really want that then you probably would 
be better off with a soft-PBX anyway.

I added it to HylaFAX+ a while back.  I also had to back off of it 
somewhat because it can cause some modems problems.

For example, ModemAnswerVoiceBeginCmd is issued to the modem after 
ModemAnswerVoiceCmd.  So, ModemAnswerVoiceCmd will be used in rotary or 
by specific configuration to answer all calls for voice.  Once a voice 
call is detected, then ModemAnswerVoiceBeginCmd is issued.  I don't know 
how to make that any more clear in the documentation.  If you have a 
suggestion for the wording let me know - I'll make a change.

JPEG and JBIG are independent of the modulation used.  So yes, you don't 
need V.34-Fax.
