Hi, I am running asterisk-1.2.10 compiled from BRI-Stuff-0.3 on a Fedora Core 5 box. We were having a problem with our firewall rules that allowed signalling through but no media when the user picked up the receiver. That has been solved now by our sys-admin guys but there were calls (SIP to SIP) that would behave in a similar way with no media. Is there anything besides security settings that could cause this? Regards, Mos
