The product is not bad, but there was a big bug in the software. Indeed the clock forward a few minutes after each external call. After a few phone calls is no longer just now. This problem is known of the support (very polite but incompetent) which gives a procedure to overcome this disadvantage. But alas the procedure does not. While the support advises to automatically adjust the time on the uap provider via the network. What? Mystery! No procedure specified by the holder or in the manual. The combined result is never on time. I think it would require an update of the software and the support staff.
