I agree that SIP kinda sucks for being a text based protocol. What about
the H.323 stack - could you not put megaco next to the breakout and write
an FSM module to handle the DTMF tones implemented as a simple user
callback module?

I played with yxa a bit and it worked ok, but I haven't used it in the

have seen a OpenSIPS/OpenSER being used embedded along with an application,
which seemed to work well.
