i have a strange Problem.
My basic Setup is: SIP-Trunk(FritzBox) -> InboundRule -> RingGroup -> VMBlasting
For internal Calls it works perfectly as expected. But for an external Call via the SIP-Trunk, there is no sound by the RingGroup/VoiceMail Announcements. If the Call was answered, everything is OK. But the Beep, recorded or Numer Announcements are muted.
If I change the setup as following; SIP-Trunk(FritzBox) -> InboundRule -> Extension -> Voicemail everything worked fine, also with the VM. All Announcements are loud and clear Unfortunately this is not my favorite Setup…
The Logs for the three Cases are by Pastebin: h t t p s://pastebin.com/9xHmiqc0
I use the following Software-Versions on an clean (Proxmox) Installation:
