Our VoIP phone system is offline due to an upgrade gone wrong. The story is a complex and sordid one, relating to Linux Debian 8 -> 9 and a 3CX SIP Switch upgrade. Stuck on 90% for two hours so far. I am working with their support people, who have been very helpful and patient with my Linux sysadmin skills (or lack thereof). The techs are in Eastern Europe and are not answering now, so this may go on until tomorrow morning.

Normally this switch updates itself automatically (thank goodness). Somehow this got bolluxed up last week on the latest upgrade. It's been running perfectly for over two years......

I'll post back when the phones are back. My apologies.
