V8 breaks previously working port forwarding schema

[tranceaddict]

Hi... I have just upgraded to v8 and am finding all kinds of errors with firewall checker that were previously not there.
Stun is not getting resolved, and one of the remote extensions doesn't connect any more.

Strange thing is that all this worked previously and have not made any adjustments to the firewall..

Here are the forwarded ports:
TCP Any -> 3478
Any -> 5060
UDP Any -> 5060
Any -> 9000-9049
Any -> 3478

Here is the server activity log:
10:27:32.048 [CM506004]: STUN request to STUN server 69.0.208.27:3478 has timed out; used Transport: 192.168.1.3:5060

Any thoughts on why stun resolution is not working. Is the 3cx Stun server down perhaps?

Is the 3cx Stun server down perhaps?

Yes it's down at the moment and we are working on getting back online running as soon as possible.
The Firewall Checker works fine if you try and use stun.sipgate.net for example.

Thank you for the response.. Iam now getting registrations and STUN resolution so perhaps the 3cx Stun server is back up??
Iam a novice as far as SIP goes but was wondering if there are still issues because extensions are registered, calls connect but there is no Audio on either end.

Could the no audio problem be also related to STUN as well even though I have registration working now for remote extensions.
I see the error of no RTP packets were received after a call is connected between two remote extensions. There is no audio between the either extension.

Thank you.

If remote extensions are set to use STUN, which they should be , and the STUN server that they are set to use is down then there very well could be audio problems. There are a number of STUN servers available on the net, 3Cx has a first and second choice , most phones and ATA's only have one.
