Hello everyone, I kindly ask for your help for a strange behavior of the fusionpbx on a voip provider called evoip.activenetwork.it. The problem is the following: I configure the trunk, I can receive calls but I can not make them, with sngrep I see that after the 407 fusion sends numerous INVITE without any response from the operator. the operator's IPs are in the acl, the firewall accepts the connections, there does not seem to be any block on the operator side. I registered the same number on another PBX (wildix) in the same network as fusion and it works perfectly at the first attempt. even comparing the INVITEs between the 2 systems I do not see anything different or anomalous, the only thing different are the outgoing public IPs (still set in fusion under the external ip item) and the port. I also tried to force port 5060, change the user-agent but without success. I attach a screen of the INVITEs. Thanks to everyone
