When you say that you can't call _anymore_ did it work in the past?
How long ago?

Here's what I could see from here:
* xen8.vandervlis.nl is listening on udp/5060
* there is a srv record published by the authoritative name servers at
ns1, ns2 and ns3.vandervlis.nl

The only thing that I noticed was that the TTL for xen8.vandervlis.nl
was 24 hours, which is why I asked about it working in the past.  Is
it possible that the ip address on xen8.vandervlis.nl has changed but
the old record is still present in some dns caches?
