[Freeswitch-users] mod_managed - how listen for *999

[Phillip Jones]

There should be no problem on digit capture on an outgoing call. For example
- when I originate a call, I ask the called party, for example, to press 1
to accept the call. This works correctly:

BLegSession.DtmfReceivedFunction = (d, t) =>
                {
                    Log.WriteLine(LogLevel.Info, "Received {0} for {1}.", d,
t);
                    if (d == confirmationDigit)
                    {
                        confirmed = true;
                        return "break";
                    }

                    return "";
                };

                while (!confirmed && BLegSession != null &&
BLegSession.Ready() && BLegSession.mediaReady() && loop <= loops)
                {
                    loop++;

                    if (!confirmed && BLegSession != null &&
BLegSession.Ready() && BLegSession.mediaReady())

BLegSession.StreamFile("prompts/press-1-to-accept-call-from.wav", 0);

                    if (!confirmed && BLegSession != null &&
BLegSession.Ready() && BLegSession.mediaReady())
                        BLegSession.CollectDigits(5000);

                }

If you are not receiving the digits - I would try and bridge the oubound
call to an existing call and check that you are getting two way audio - and
if you are using inband DTMF -  that you can actually hear the digits.
