There's another STUN server that resolves to the same IP:

New installation of v16 on an Intel NUC using the Debian ISO. Attached to 3 Grandstream GXP2135 phones, using a Wiretap SIP trunk. Everything seems to be working OK, but my logs keep getting filled up with these "There's another STUN server that resolves to the same IP:" errors. The firewall checker has passed with flying colors. Any suggestions? I did a bunch of searches beforehand, and only found one person who said "That's expected behavior, ignore it". I don't generally think your logs should be filling up with anything, especially errors. Thanks! Pic for detail.

Do you have static IP or dynamic IP selected for your installation?

 

[jcayer]

Thanks for the response, Its set as dynamic currently. (Residential broadband service)

So that being the case I don't think there's anything you can do about that. I agree it's a bit much on the log spam but I honestly never look at the logs unless I'm troubleshooting something and they are rotated so I wouldn't worry about it. I don't have any dynamic setups to confirm the behavior though.

Is there any information (another part of the logs), as to what the STUN server IPs are? I'm assuming that they are 3CX STUN servers. 3CX allowed multiple STUN servers to be datafilled, could there be duplication in those settings? By default, I wouldn't think this would be the case.

Hi

The log message you see is indeed normal when you are set to Dynamic IP mode, as one of our STUN server FQDNs resolves to two IPs, one of which is also under another STUN server
