Hi all,
I'm trying to use openser with Audiocodes 3000 as pstn gateway.
This is my scenario:

UA----------->  openser-------> MGC-------->Audiocodes-------> PSTN.

When I use Asterisk as PSTN gateway I haven't  any problem for rtp 
traffic, even when UA is behind nat.
Using Audiocodes I noticed that the rtp traffic doesn't flow from 
Audiocodes to Openser (or viceversa), but the rtp flow  bypasses openser.
This cause problems when UA is behind nat because mediaproxy doesn't fix 
nat.
All my outbound calls are redirect to MGC, and in my route section the 
Audiocodes's IP address doesn't compare.
My questions are:
is this an Audiocodes problem? .... or I can adjust openser 
configuration for fix that?

Thanks for your attention.
Regards,
Stefano.
