Callweaver assumes that SIP channels support T.38 by default.
AFAICT there is no way at the moment to use T.38 on one SIP leg and ULAW
on the other (the fact it works in the case where you dial Verizon, is
because they have to send you a T.38 re-invite, and they don't). You can
however Set(T38_DISABLE=1) before Dial()ing the mp114 and the fax should
go over ULAW the whole way.
