voxalot.com STUN server is unreachable

It seems that voxalot's STUN server is unreachable. That's fine for most SIP UAs which have an option to configure STUN manually. But if you want to rely on DNS - no way :(

Code:

$ nslookup

> set type=SRV

> _stun._udp.voxalot.com

Server:         192.168.5.1

Address:        192.168.5.1#53



Non-authoritative answer:

_stun._udp.voxalot.com  service = 10 100 3478 stun.voxalot.com.



Authoritative answers can be found from:

voxalot.com     nameserver = ns2.voxalot.com.

voxalot.com     nameserver = ns1.voxalot.com.

stun.voxalot.com        internet address = 202.60.88.239

Did you try stun.voxalot.com.au ?
This one is definitely working on my ATA.

I do not believe that there is one at stun.voxalot.com though the website could probably be a bit clearer about this.

Hope this helps ....

What for? I'm talking about specific problem with the server provided by DNS.

This is not about the user who can't use specific STUN. This is about the invalid server reported by DNS.

You don't even have to believe ;) Just follow the procedure I described and query DNS yourself.

stun.voxalot.com and stub.voxalot.com.au both point to 202.60.88.239 and is definitely reachable.

Not sure the same traceroute reports fine from the U.S and AU:

Last hop is also the same. Interested to see other peoples experience?

Looks fine here.

Fine here too on my Aussie People Telecom connection which sometimes tends to have the odd routing issue. I can't get to some ipkall pages for instance, but my Exetel connection gets there fine.

It seems that one of our networks (/14) is filtered there:

If anybody from Admins is willing to help please let me know. Thanks.
