We starting using Zulu recently so people could easily work from home.
Several times per day, every user is disconnected from the server (any calls are dropped), and Zulu reconnects about 5 seconds later.
2020-08-06 12:03 -07:00: TypeError: Cannot read property 'getVariable' of undefined at CallManager.blindTransferfn (/var/www/html/admin/modules/zulu/node/index.js:1:181192) at emitThree (events.js:136:13) at EventEmitter.emit (events.js:217:7) at _combinedTickCallback (internal/process/next_tick.js:138:11) at process._tickDomainCallback (internal/process/next_tick.js:218:9)
I’m not sure if that’s the cause or a symptom of the issue. For some of the affected users we also have Digium D60 phones on their desks. D60 phones do not lose their calls, but Zulu does.
