I reported it to the provider but I haven't had a reply to date and I'm going to remove them from the zone after I post this.
Second thoughts, I just tested voip.trxtel.com and it's working again, it stopped working at one stage and the provider never replied to me so I removed them from the zone as well ages ago.
PS can any problems with data in e164.org please be reported to support@ so we know there is a problem and can deal with it sooner then later
