Erratic incoming calls, regular interruption of outgoing calls

Should you encounter problems after the configuration, like irregular incoming calls, regular interruption within a call etc., please check the parameters on your VoIP device, router or firewall. In general you need to:

  • Deactivate the firewall and/or router: SIP ALG
  • Activate the device: NAT Keep alive
  • Activate the Gigaset IP: STUN server with stun.peoplefone.com

Disable SIP ALG
