sip module only works for a short time

Hello all,

I use a Fritzbox behind the XG with PhonerLite or LinPhone as SIP client. My provider is 1&1.

Unfortunately, I have noticed that the SIP module crashes after a short time and that I only hear the ringing on new calls, but not the person I am talking to.

I have now searched through the logs and found that the telephony works until I find the following in the log:

localhost kernel: [266259.312048] ip_nat_sip_expected: doing self nating: <212.227.124.5>
localhost kernel: [266261.783797] ip_nat_sip_expected: doing self nating: <212.227.124.5>

Does anyone have any idea what the problem is here?

Regards
Marc

  • Maybe I am missing something, but your error message is from your voip device not the XG, correct? So maybe you need to disable Nat on your voip device?

    the error message would imply that you have the voip device wan interface connected to the XG, not the lan interface.

  • No, the log is from the XG itself:

  • It seems that I found a solution now.

    I have set in the Fritzbox "Keep port forwarding of the Internet router active for telephony" from 5 minutes to 30 seconds.

    Many thanks to all for the support.
