I've just spent the best part of two days searching for that elusive Skype-to-Phone replacement and Localphone plus their softphone app on my PC was in the lead until I ran into trouble installing their softphone app. I too read the TrustPilot grumps about customer support so I was surprised and delighted when they followed up an instant automated response to my report with really helpful emails from real people with contact details so I could address them directly. After checking the version and update details of my installed Windows 10, Alan, told me that a recent Windows update had rendered the softphone inoperable and although they had their developers working on it, it wouldn't be a quick fix. Finally, at about midnight UK time, Rikki Agustin, the sales manager sent me a useful set of third party softphone installation screenshots. Very helpful. (I can't spare the time to check, but I suspect the Trust Pilot critical service reviews were all fairly old so don't overlook Localphone)
