Good question. I can't offer any experiential data having never tried it myself, and I have no insider info either... butdman76 wrote:In the account preferences section if you go under phone numbers and click Telo, what is the difference between the three modes (phone, fax machine, and alarm system)? I haven't tried alarm system but if it is on fax, it seems to work for voice as well and you get a normal dial tone instead of the Ooma one. If they all work for voice, just wondering if there is any disadvantage to not use the phone mode.
if I were to guess based on some logic, I would venture that it might have something to do with the codecs and algorythms employed on a per call basis? Also, I would imagine it would help the customer service department with call metrics.

Perhaps some variation of " Use low-bandwidth codec (iLBC) for this phone call" vs. use High?
Certainly "Optimize phone call for fax transmissions"
If that's anything in the way of an unofficial answer for you
