Devon Dave, your reference to 'for Joe Public to access' intrigues me: I didn't know there was even a way of logging incoming calls to any given number, to be accessed by Joe Public or otherwise. That aside, for the ( possible ) benefit of the original poster, it crosses my mind that one possibility might be for the arbitrator to request outgoing call records for your employer during the period in question. Of course, this hinges on two things: firstly, I don't know how much power the arbitrator would have to demand these records if the employer was reluctant ( as they presumably would be ); two, even if this is a do-able thing, it's only really practical if your previous employer is relatively small - going through four months of outgoing call records for Fred's corner shop is a lot less cumbersome than going through four months of outgoing call records for, say, the DVLA.
