[Freeswitch-users] DTMF does not work from PSTN(cellphone or your home phone)

Tue Mar 26 11:41:19 MSK 2013

Hi Sayyed,

I think to capture the DTMF packets you will need to remove the port 5060
from your tcpdump.
You should then lookout for the RTP events in the log, wireshark is a great
tool for detemining issues like this.

Also, as suggested by Victor, have you checked with your SIP provider which
method they use to send the DTMF?
If they are sending inband and you have not specifically set to listen to
inband in the dialplan (start_dtmf), then Freeswitch will ignore them.

thanks
Matt
