Aha, thanks - I shall try this soon
Let's be clear - I didn't have this hang-up problem at all with the CallKey phone on its own, so I have no complaint against them at all.
It was only when used with a different callback, and then did not occur after callback was used to the forwarded O2 phone received on the IoM number. I'll mess about with it a bit later on; it would be good if it works, as if they later introduce caller ID, then less need for O2 as well to have the range of callback methods or protect this hang-up issue.
