Grandstream transfer solution + DTMF translation possible?
The solution to the problems with the Grandstream 1.0.4.39 firmware is
to use inband (in-audio) DTMF. Neither the RFC2833 nor INFO seem to
work.
However, this presents another problem. When I'm using g729 to place
a call, I get the warning "Unable to process inband DTMF" because
inband is not supposed to work with g729 (although it does seem to
work when I've tried it so far).
