Wrong routing to +49800...
 

There are DNS entries for 0.0.8.9.4.e164.org which cause the whole +49800 number range to be routed wrong. sipgate.net and pbx-network.de cannot route such numbers. Who has entered these DNS records???

I did, sipgate was for the longest time allowing +49800, but they suddenly stopped and didn't give us notification that they were no longer accepting calls.

The system was setup to give both providers equal amount of calls due to DNS round robin, so it should have worked in theory at least 50% of the time, more then that if fail over was able to occur.
