I was going to create a new topic but forgot that I'd asked this ages ago. So revisiting the same question - since it's been quite a while, are there any new recommended softphone options for a 5000, to replace the 8602? We've since purchased the MiVoice Office Application Suite, along with some various phone manager licenses. But even with a phone manager 5.0 client in full softphone mode, we still find it lacking in usability and "desk phone replacement" functionality when compared to the old 8602. Also tried bria v4, and 3cx. All of the SIP type applications just don't seem to be as tightly integrated.
