[Freeswitch-users] IVR to hunt group to external destination fails // direct to hunt group to external desitnation succeeds

When a hunt group is accessed from the main IVR, the hunt group dials an internal extension via transfer correctly but when trying to dial an external number such a cell phone via sip uri it is unable to connect or ring the phone but it waits the correct timeout period before it goes to voicemail. However, if you access the hunt group directly without going through the main IVR, all works perfectly. Any ideas where I should look and what line of code I might be missing? Thanks, -Will
