Most birds have a fight or flight response.

He forgot we’re flightless birds.

8x8 is now on my list. They claimed to have scanned my badge at Enterprise Connect, but I don't recall stopping by because they're a competitor. They emailed me Thursday, I immediately unsubscribed. Within 5 minutes they're calling me and they've called me every business day since then.

Flashback to 2013 when people still used XM Radio for music on hold for Cisco Call Manager. I had to build a stereo to mono converter for this one. Think it's still in use today.

Indeed.

This morning at Dept of Housing and Urban Development (HUD) HQ in DC as mandatory return to office began, this video played on loop for ~5 mins on screens throughout the building, per agency source.

Building staff couldn’t figure out how to turn it off so sent people to every floor to unplug TVs.

Guess I should post some actual collaboration stuff, eh?

Best upgrade of year so far: CUCM 9.x (EoS 2018) to CUCM 15. PCD 15 doesn't support 9.x, but PCD 12.6 does! PCD 12.6 from 9.x to 12.5.1, then PCD 15 from 12.5.1 to 15SU2.
