reason for dialup issues?
from my understanding dial up will not work on a cell phone in similar ways that it will not work with a voip system we once attempted to make a dialup call with a voip phone modem just for testing and it was a no go. the main reason for this is the call will not have the fidelity of a line due to the compression that is used during transfer their would also be a delay that may cause issues. the best example is if someone holds the cell put to a radio/band you cant hear whats going on very clearly due to the compression. correct me if im wrong... it happens alot
