Reporting SUCCESS: “mini-HowTo” in a nutshell

  • Firmware-upgrade Gigaset DX800A
  • Firmware-upgrade Gigaset S850A GO
  • Firmware-upgrade CISCO SPA122
  • Make sure that all devices exploit their SIP / RTP ports being totally unique
    throughout the whole NAT-internal IP range (they should all reside in “orange”, btw!)
  • Make sure that “STUN=disabled” in all devices
  • Disabled all ALGs including SIP in Core Update 154
  • Final test: Shut them all down → power off; re-start with IPFire, …
    accept calls / FAX from external
  • Ultimately I felt relieved :slight_smile: :

Now I’m positively looking forward to Core update 155

NOTE: No port forwarding rules introduced into IPFire at all !
