I had a working FS installation which I messed up by doing a fresh install. I tried to integrate all my custom changes, but I'm sure I screwed something up. The symptom is on an outbound call, sometimes I can hear ringing, other times I cannot. Finally I can see FS connects via a softphone, but I hear only silence. The other side of the conversation hears static. I pasted a siptrace of the external profile. The Contact, Via and SDP shows an address 0.0.0.0. http://pastebin.freeswitch.org/9318 FS exists on a LAN behind a NAT firewall along with all its clients. There is a SwitchVox system which predates the FS. I had to use an external sip = 5090 for FS. Also I think I had to use a different WAN address (xxx.xxx.xxx.83, which is the address mapped to 5090) than the one FS came up with (xxx.xxx.xxx.82), but I can't figure out where I set this address. I would appreciate any help. Thanks, Lars
