Methinks your difficulty finding an ITSP for this purpose is directly
related to said ITSP's collective experience trying to get this to
work for their customers. They've no doubt discovered that the support
costs for the many times that they have to deal with a broken T.38
implementation or an intermittently lossy end-to-end voip connection
are more than the marginal charges they can assess for the service.
