Hi! I'm using Fusion to configure FreeSwitch and encountered a bug, that MIGHT be related to FreeSwitch. Idea - I have an extension with ring group on it made this way bridge({ignore_early_media=true}[sip_invite_domain=pbx.securenetvox.net ,confirm=false,leg_timeout=30,leg_delay_start=0,dialed_extension=108,extension_uuid=c728abd0-6107-460d-b1b6-4861c6b6998f]user/ 108@pbx.securenetvox.net,[sip_invite_domain=pbx.securenetvox.net ,confirm=false,leg_timeout=30,leg_delay_start=15,dialed_extension=107,extension_uuid=4bd03430-767b-41da-8b78-0902d590cdc2]user/ 107@pbx.securenetvox.net) And on extension 108 i have a custom dialstring: {presence_id=0038091908XXXX@pbx.securenetvox.net ,instant_ringback=true,domain_uuid=32ade86a-9d28-4468-9fc9-2a39fe9ffe50,sip_invite_domain=

pbx.securenetvox.net,accountcode=pbx.securenetvox.net }loopback/0038091908XXXX So, I dial from extension 107 to ring group extension and got this (part of log): ............. 2015-10-05
