[Freeswitch-users] Unknown call drops.. INFO DTMF(3)

[Mark Campbell-Smith]

Hi!

I have just experienced some call drops and each time the sequence is
the same in the freeswitch.log file.  Both parties are sure that they
did not accidentally hit the 3 button to send the DTMF tone (and the
same thing has happened four times already after ~5 minutes).

Anyone have any idea what this sequence means and why I am getting
this?  Is it my sip provider or something in FreeSwitch?  What does
the 'Send end packet for [3] ts=2591120 dur=13120/13120/13120
seq=65006' mean?  Notice that dur (duration?) is increasing a lot
until the call drops.

Thanks!
