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,domain_name=pbx.securenetvox.net,domain=pbx.securenetvox.net,extension_uuid=c728abd0-6107-460d-b1b6-4861c6b6998f,toll_allow='',sip_h_X-accountcode=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):

So, at some state original channel info is lost.... Is this a bug or something another?
