[Asterisk-Users] Send dtmf to ata186!!!

[Erick Weber V.]

Hello:

I have problems sending dtmf signal to an ATA186 my configuration is:

ATA186 --> asterisk --> ATA186 --> FXS to FXO Converter --> PSTN

The ATA186 are set to send dtmf RFC2833, but it seems that the ATA186 can't 
generate dtmf.
Is there a setting that can fix my problem, inband dtmf does not work 
because I'm using G729 codec

Thanks

Erick
