Hi All! I have 1.6 version.My config- Elastix with local client behind nat, client behind another nat. Outgoing calls from local client thru elastix to another client behind another nat go perfectly but on the contrary it works during 20 sec and elastix hangups. I googled all the internet and saw many explanations,advices etc why it is. Nothing helps! I downloaded 1.3-2 version,installed,made portforwarding and it works!!! I didnt even touch sip_custom.conf,sip_nat.conf etc. I mean it works wrong! I tried 2.0alfa3, 2.0beta1-all the same. Does Nobody see it? May be All use outgoing calls only...but i need inbound too.Where is the reason? Thx in advice. ps-In 2.0beta1 i could not even make local calls to each other.
