[asterisk-users] Dial problem

[Rilawich Ango]

HI,
  I have 2 TDM400s plugged in a PC.  I failed to use same channels to
make a call to PSTN.  It shows it can't establish connection after
dial command issued.  Below is the log.  Actually, the call is
established as I can hear voice from the called party but the
softphone is still showing ringing.  It seems the TDM card can't get
an answered signal from PSTN.  After 15 seconds, the call dropped
because there is no answered signal.  I want to know how to handle the
problem? Is it related to settng?  Can anyone tell me?
