"This is a fundamental change that means the older tech (Skype Certified phones) won't work on Teams."
that CP960 though.
obviously these devices aren't hardware limited like they're running some hypothetical ASIC that only speaks SIP. There certainly could be a fundamental change preventing companies from developing teams firmware for existing skype phones but it's not a technical one. it's a money one.
in the yealink world at least the T4 series has full Opus codec support, but they want to upsell T5 series instead so they just don't develop a Teams firmware for T4 and then some sucker comes along and throws in "certainly a downside of fast evolving technology" as if he's not literally wrong and there should be some gestalt world-wide knowledge that companies are allowed to hand-wave away any criticism with "agile devops synergy oh well hey look new shiny" instead of fixing their broken business plans.
