Mac OS X for phone/voice calls (mobile phone, POTS, VoIP): progress in the decade since Panther A few points on a timeline: 2003, October: Apple Announces Mac OS X Panther 2004, October: BluePhoneElite beta 2005: I used both BluePhoneElite 1 and Jon's Phone Tool (JPT) 2008: transition from JPT to Leopard-compatible Dialectic 2010: end of availability of BluePhoneElite 2 2014: limited continuity of calls with OS X Yosemite note, transferring a voice call to an iPhone is not a handoff. Essentially: using a Mac with a phone is not a novelty. Thoughts I was surprised to read that OS X Yosemite does not feature transfer of calls from iOS. I wonder why the years of development, of the two operating systems, have not resulted in better continuity. Given the history years of development, with some constraints that are beyond the control of Apple how do you feel about the limited ability of Yosemite to work with mobile phones? I'll add a poll to this topic. A few links and quotes In Wikipedia: mobile phone plain old telephone service (POTS) Voice over IP Under Apple's Software Quality Decline: To me it's not exactly a decline, it's more a lack of progress.

" One of this unique feature is making calls through Mac, using the cellular network " Handoff & Continuity: Finally phone and computer are talking to each other - The Times of India (2014-06-03) I routinely used the Mac OS X Address Book, or third party software with that application, to initiate calls years before Yosemite was previewed. " Calls can be initiated from the Contacts application " http://arstechnica.com/apple/2014/10/os-x-10-10/19/#iphone-calls 2015, folks. I'm disappointed that Yosemite can't work with iOS in that way. I suspect that in the Steve Jobs era there was better recognition of the differences between Mac hardware and iPhone hardware.
