I have PSTN's but what is this...

[scu]

I am only using two PSTN lines and my server logs shows this ever 10 seconds.. what is it that I missed? It says that to disable STUN, delete the entries, so I don't have an entry in the STUN settings under General Settings Page except for the Port Numbers that won't go away.

Anyone please tell me what I can do to make this go away.. again, it goes every 10 seconds..
I have a Grandstream GXW 4104 Gateway, with 3cx Ver 5.0 Build 3790. Thanks.

Go through the firewall checker and ensure you pass?

I suggest upgrading to 5.1. You can then remove the stun server check by emptying the stun server setting in general settings, this wil make the check stop.

Thanks I'll try upgrading, though I am a little hesitant to upgrade because of the uncertainty of previous updates, I think I will just go for it ..

We are running Version 5.1.4128.0 with no entries in the stun server options under general setttings (the port numbers keep regenerating in the fields) and we are scrolling the same message "There is no valid STUN server specified! External IP can not be resolved."

Bump

I have the same issue... in one of my external lines (out of the home-net) I get the same error: There is no valid STUN server specified! External IP can not be resolved.

 

[banksy]

We are getting the same problem.

We have a static IP no nat, so have no reason to use STUN, infact our provider requires us not to use stun.

Any suggestions? the field are blank

 

[josvic]

Any suggestion?

The function cannot be turned off. You need to have the stun address, or set the delays between each stun high.
