[Asterisk-Users] DTMF method AVT

[Joseph]

What kind of DTMF method signaling is "AVT" ?

My Sippura seems to support only InBand, AVT, INFO, InBand+Info, Auto
INFO does not work with Asterisks voicemail system so it is useless for
me.

InBand - I have a problem with this one when I try to connect to a bank
automated systems (some of them don't recognize this one).

When I set asterisk to "rfc2833" dialing out works perfectly but when
somebody tries to call me and dial an internal extension, it is a 50/50
(sometimes it works and sometimes it gives me invalid extension).

I'm using Asterisk-1.0.8
