Hi all, Ever since upgrading past 1.6.6 I've had problems when using the originate command. I'm unable to hear ringback on the call and no channel_progress ESL event is emitted when the "183 Session Progress" message comes back from my SIP provider. Once the call is connected I can talk as usual. Here are the console outputs; 1.6.6 (working) https://pastebin.freeswitch.org/view/3998aa81 1.6.9 (no ringback) https://pastebin.freeswitch.org/view/65002d96 Thanks in advance
