Hi, Please sync DTMF settings with the carrier. If carrier is using INFO but your settings is INBAND then you will only receive if DTMF as voice if the far end is sending it INBAND. Regards, Faisal On Tue, 9 Jun 2020 at 05:07, <stephen@picardogroup.com> wrote:

Have built a new FS box using debian 10 and FS 1.10. We use Flowroute as carrier. On outbound leg we always connect to number dialed but sometimes we do not hear the DTMF being sent in return.

So question is: What could be reason why freeswitch is recognizing DTMF signals received from some endpoints but not others?
