In most cases the above has worked fine (we also use a 15060 -> 5060 remap), but I have one user for whom nothing seems to work. The problem has persisted with different models of CPE, different phones, different server-side ports (5060, 5061, 15060). They even moved and the problem followed them to a new house (albeit in the same area). I was never able to work out the issue and have been assuming it's a regional problem in Uverse (in this case it was near Austin, TX). IIRC, the user ended up switching to cable. Dan
