I believe you, but that shouldn't be. True end-to-end voip between a
pair of voip phones will be much cleaner than any POTS conversation.
After all the phone is doing the ulaw encoding in the phone a mere 3
or so feet away from the phone's microphone. You don't have 14kft of
wires to pick up stray signals before the ulaw conversion is done at
the telco.
For the best sound you do need to check that whatever service you are
using is using ulaw encoding. If they are sending compressed data,
you are going to get lower quality than pots.
