Also in terms of ping times how far is the PSTN gateway, as Bogdan said,
media proxy will add even more delay, as for sending pstn via
mediaproxy, you could do all yourprocessing, and once ser detects that
call must goto PSTN, then do all the NAT checking ...this is a
oversimplified view...

Hi Ozan,
so, if I get it right, you have a PSTN gw locate far away from the
UAs...and instead of letting the media traffic to do directly between
GW and UAs, you want to insert in the middle a RTP relay (mediaproxy)
in order to improve the QoS, right?
If so, I would say this will not help you - having a media relay on
your media path leads to QoS degradation due additional delays....
If you still want to go for it....I will take a look on tour script.

Dear List,
At below config. i setted up OpenSER on Public IP and PSTN Gateway is
again on another Public IP. I use Zyxel Prestige Series 660-HW ADSL
modems on both client side and note that they have SIP ALG, also i've
completed port forwarding in each modem, so SIP2SIP call happens
(voice traffic goes from UA to UA) without need of anything extra as
STUN or RTP RELAY. But since those are very away from each other if a
UA needs to call PSTN the voice traffic flows from UA to PSTN and
that lowers QoS :(
I would like to activate MediaProxy again but just for one case which
is PSTN, so whenever a UA needs to call PSTN the voice traffic flows
like :
UA (ATA) >>> OpenSER + MediaProxy >>> PSTN
How can i setup this like above without touching SIP2SIP calls
between UA's...
or adding the lines beginning with # these to my existing config is
enough ?
Thanks,
Ozan Blotter
