After switching from e.g. Preferred Cluster eu.voxalot.com to us.voxalot.com the call forwarding works fine for a while approx. one hour. Then it breaks and a voice at Voipfone says "Sorry, the number you have called could not be connected! Please try again".
Switching back from us.voxalot.com to eu.voxalot.com resolves the problem again for approx. the same time.
I tried nearly everything without success!
Please help!
