STUN Problems - urgent!

[Zebramanager]

Hi,
my 3cx ver. 5 is not connecting anymore to the STUN Server.
When I check the debug it tells me with red: STUN check failed. Unable to contact STUN.

Please help! It is urgent.

Regards

Zebra

hi,
I had this problem too.
Put stun.xten.com (for e.g.) instead of stun.3cx.com to solve this problem.

another that we have found to be rock solid is stun.counterpath.com

Thanks for this quick answer, but do you think the problem will be solved soon?
I would have to contact about 100 partners to change the settings and it is not that easy. I will do this only if the problem won't be solved in max. 24h.

Thanks again.

I experienced same problem as of today, though no settings changed manually in hardware or software. Previously had no problem connecting to network (gizmo) using 3cx softphone. Still no problem rec calls using Gizmo's own client, so gizmo appears to be working. Tried reinstalling 3CX telw v5. Also tried changing STUN settings to those recommended by other forum users; that led to 'authentication failure' vs simply 5 failed attempts to connect each time. Gizmo claims its stun port is 3478 but no evident way to incl that in 3cx config; tried making stun setting in 3cx first stun01.sipphone.com and then stun01.sipphone.com:3478; both failed. Please advise.

Fol is debug:
