Yes, I personally saw it work successfully (I wrote the code), and know
it has been deployed on many systems. Maybe you should ask the other
end why the other end is saying RLT not allowed?
Also, you have to make sure that it is between an inbound call (to
Asterisk, from DMS) and an outbound call (from Asterisk to DMS). It
should already check for this in libpri, but I figured I'd mention it
just to be sure.
