[Asterisk-Users] Re: DTMF, Asterisk, External PSTN gateway, and PAP2

[Sherwood McGowan]

Very interesting. I've already challenged him on it, since I found several
things online (including the "Hitchikers Guide to Asterisk") that said
rfc2833 was better and that inband was generally not suggested. 

After reading that, I would have gone with rfc2833...I'm not sure why he
didn't....
