Apart from a few numbers I don't talk on the phone for long periods of time. With one particular number - my most called one, also on o2 - I find that calls are dropping multiple times in the 1 hour or so call. Sometimes it's clearly a signal issue at their end when they are in certain buildings but other times it's not so clear.
Sometimes I hear 3 beeps before it disconnects, does this mean it's an issue at my side?
Is there anyway to trouble shoot this issue and work out where the problem lies? I've checked the status checker for both our areas and it's come back fine.
