We have found a fault today with Vodafone 3G Calls to WorldxChange Numbers
The issue would have shown itself as no Audio and would have been occuring since early this morning.

The issue was random and appeared only on some of our circuits and only on one of our points of interconncets, the issue took some time to identify as it was rather complicated, the issue is now with Vodafone and relates to some new circuits they put in last Night, They are now working to fix the issue.
