[Serusers] Strange problem - SIP-->PSTN - 40 sec calls duration

Hello!

When i'm trying to call from UA to PSTN i have a call failure after 40 sec. All my UA's (private and public ip) works fine when calling each other. Calls from PSTN ---> UA's also works fine. But when i'm calling to PSTN i may talk only 40 sec. I'm tried from NAT UA's and UA's with public ip, softphones and ipphones - same result. I don't know what to do, someone please help me.

UA (Sjphone) - 192.168.97.88 (symmetric nat) - 211.211.211.211 (outside ip) Openser - 212.212.212.212 PSTN Gateway (Alterteks CallSwitch)- 213.213.213.213
