I am constantly getting this error on a new build of FreePBX 13. I have removed trunks and it still continues. Any idea to fix this would be greatly appreciated. I do have many commercial modules installed but at this point don’t even know where to start.

Ever get this resolved? I’m seeing the same errors.

We are suffering this error. Any idea to solve this? I’ve heard about trunk configuration, but it’s the same config we use in all freepbx machines we have in production, and this error is not present in anyone. Suggestions? regards

I’ve tried to set on and off, and got same result. :frowning: And yes, we are sffering issues, like some daemons stopping: ucp, xmpp, zulu amd restapps :frowning: Any idea?

Sorry to hear. We’re not using UCP, but seem to only have them on the servers in the environment explained here: [image] Consistent Asterisk/FreePBX Crash Issue Running FreePBX 13.0.192.16 and Asterisk 13.17.0 Recently used the "warm spare" method to move to a new server (new VM on KVM/…

Well, I have relized that the errors are originated from the same IPs. They are allways the same and they are connected via VPN, like other extensions. Regards

Hi Steven, We are using Yealink phones, T23G are all of them, and we use a local SIP provider, in Europe. anyway, we thnink we have not issues with endpoints. we think zulu’s PCs are who originate this issue, but it’s just an opinion. We have blocked some IPs and it seems to be a little more stabl…

Oh, I was referring to the internet provider, no the SIP provider.

Internet provider is local provider as well. Same provider for both services. Anyway, we don’t think it’s a provider issue. We have several Freepbx machines working in the same datacenter, with same provider. Regards
