[Users] inbound call failed

[unplug]

I think it is the NAT problem, so I use stun for the case below.

Telephone (A)
  |
PSTN
  |
G/W
  |
openser
  |
NAT -- IP phone(B) -- STUN
  + ----- IP phone(C) ------+

Below is the result:
A to B/C is ok
B/C to A is ok
However, there is no sound when B to C or vice versa.  What reason
will cause no sound between B and C?  Is the the reason from the
NAT/STUN?
