Of course in theory it shouldn't make any difference if the conversion
from analog to digital happens in the box in your house or at the local
bell building. Assuming of course that they implemented it the same
way in both placed, which they should, but maybe they didn't.
I have seen multiple people claim fax machines work over thair VoIP
connection, which surprised me, because I was under the impression that
they didn't. Apparently some VoIP systems actually are fully compatible
with what the phone system has been doing at the central office and
hence work with the exact same equipment as the "analog" phone line did.
If hasn't really been that analog for decades after all.
Again, what is the problem we're trying to fix? I have heard nothing
about why emulated POTS won't work. As far a FAX goes, I heard the same
thing, but I've never seen it fail, even though I have installed VoIP
PBX, where the customer was still using FAX. A standard toll quality
POTS line has a bandwidth of approximately 300 - 3500 Hz. VoIP has no
problem meeting that and in fact there is now "HD Voice", where VoIP is
superior to POTS. Again, I have worked in telecom for the past half
century. Until we know what the issue is, we're just guessing.
What specifically is the issue with this equipment???
