[Asterisk-Users] INBAND DTMF G729 ASTERISK

[Michael D Schelin]

Hello, I'm not sure about Asterisk and in band DTMF without careful 
reading, but i do know that most ATA's and soft phones all have in band 
capabilities if set. G729 may not pass in band DTMF correctly all the 
time,in fact it's very poor and this is the reason for out of band. I 
think from reading the rest of the comments on the this post that you 
may have to look closer at encryption to keep all eyes from sniffing out 
the pins. I understand why you wouldn't want to slow down VoIP any more 
than you have to but customer security is more important.
