I'm hoping someone might have seen this before but as the title suggests when some phones attempt to make outgoing calls, the call fails and "ERROR" is displayed on the handset. Sometimes it happens just as people answer the call, other times it happens as soon as they have finished dialing.
There is nothing obvious in the logs that I can see, and wireshark isn't much help as it doesn't decode Minet packets so all there is displayed are heaps of UDP packets but not much else.
Phone provider cannot see any issues with their side of things (which even if there were errors they would hardly admit them).
This has started happening since the controller was moved from a physical to a virtual controller.
If anyone has any suggestions as to best diagnose this error it would be greatly appreciated.
