Adding to what I already said, just tested that Asterisk indeed doesn't
translate between inband and rfc2833, here is the setup:
Analog phone<->SPA-3000fxs(g729,rfc2833 friend in sip.conf)<-Asterisk->
<->anotherSPA-3000fxo(g711alaw,inband friend in sip.conf)<->PSTN
Calling from PSTN, and into the FXS port's extension:
a.b.c.d 54321 74acc9957be 00102/00000 g729 No Tx: ACK
e.f.g.h 123456789 f10b0644-47 00102/00149 alaw No Tx: ACK
DTMF sounds get muted within 20-50ms and what is left is high-pitch
burst. At the same time, DTMFs from FXS extension sounds same, but generate

Resume: while all-g711/inband and all-g729/rfc2833 setups work
flawlessly, mixed setups are broken. It's not a Sipura issue too, as
adding canreinvite=yes makes the devices communicate correctly. Same
thing with other FXO gateways.
