Dear all, I'm working with FS since a week. Hope, it's ok to use it in FusionPBX ;-) I found out many cool things so far but with one thing I'm stuck. I'm not able to initiate a connection from innovaphone devices (1 deskphone IP240 and 1 PBX/GW IP800). Calling to these innovaphones is ok. From other devices to FS and softphones I can connect too. In my first try from the innovaphones I got the message 2018-11-10 23:41:58.763840 [WARNING] switch_core_media.c:4181 NO candidate ACL defined, Defaulting to wan.auto 2018-11-10 23:41:58.763840 [NOTICE] sofia.c:7774 Hangup sofia/internal/11@pbx.[anonym].net [CS_NEW] [INCOMPATIBLE_DESTINATION] I found the solution to put apply-candidate-acl=localnet.auto to the internal SIP profile. I don't understand why this was necessary only for the innovaphones and not for other devices but after changing this I can establish a connection but cannot hear anything on both ends. After a few seconds the connection is disconnected automatically. Here's the log. I hope, someone can help https://pastebin.freeswitch.org/view/db088714 Best regards Daniel
