Symmetric NAT Handling Disabled = break SIPBroker
I'm current using SIP Broker as my VOIP for dialing 1800 numbers. When I set Symmetric NAT Handling to YES, I can make these calls but when I set it to NO I have no Incoming audio. I've successfully made calls with other providers when turned OFF Symmetric NAT Handling and audio optimization ON. Any else experiencing this problem?
