Someone posted this question a while ago and I cannot find the post or who sent it but here is the answer : .
R6.5.22 using DTMF digits and they are not sounding right .
We do not pass dtmf from an analog device ( INternal ATA ) to a 31xx type of device but we do pass dtmf from analog to analog devices. ( tested out FXS to FXO - ATA to TLIM and FXS to FXS - ATA to ATA .
I tested in my lab and found that from an FXO ( internal ATA ) that the digits were fine . I tested dialing out to another system and using the AA via the FXO - TLIM internal ports . Everything seems to be fine .
No DTMF issues found on either internal or external analog devices .
