One more issues with SBC functionality                
                Good evening.
In following configuration : 
ROUTER with NAT (full cone)
SBC(ipva) for example with ip 10.111.111.2
 PBX (ipva) for example with ip 10.111.111.3
-
On Sbc configured STUN and Two session border objects with 
mapping to PBX and enabled media relay option . 992 and 993 SIP extensions which register from internet over SBC to PBX .
In case if 992 call to anywhere and even to 993
SBC dont care about STUN settings and send inside SDP PBX ip address. Result : 
No voice. 
Can you please point me what i forgot to configure to force SBC to insert Media ip which was detected by stun setting ?
