[Freeswitch-users] FS 1.0.6 on EC2 - no audio on outgoing calls

Hi there, I am experimenting with FS on EC2, I like results, but stuck on weird audio issue - I followed FreeSwitch EC2 wiki article and modified internal profile and vars.xml accordingly, but unfortunately still cannot get it working. Incoming and outgoing calls made using a SIP phone to FS extensions work just fine. As well as calls to FS from PSTN. But calls to PSTN via gateways result in no audio at all, no ring, nothing, SIP signaling goes through OK. Sofia status profile shows correct values for Ext-RTP-IP for both profiles - my static public IP, RTP-IP shows local IP. Any thoughts on that? Anybody can share working profile configuration may be? Please help, I really need to get this going. Thanks.
