[Freeswitch-users] DTMF not comming through on some calls

[Andy]

Hi,
 
I have an urgent issue if anyone can help. I have been running  freeswitch
for 3-4 weeks now without issue. In the last 2 days some of the calls coming
into the switch seem to get set up in such a way that means they cannot
carry DTMF. ie on that call, no dtmf signals come through from the phone.
It's not that digits get dropped some calls semm to handle dtmf perfectly
and others don't seem to get dtmf at all.
 
Can anyone shed any light opn this or suggest any solutions?
 
Many thanks
Andy
