In case you haven't noticed yet, telegram adapter current version 1.10.0 can not make calls via callmebot. The issue has been reported also here: https://forum.iobroker.net/topic/45059/telegram-adapter-kann-keine-nachrichten-schicken/15?_=1629158512705

When trying to make a call, it throws the following errors in the log:

TypeError: Assignment to constant variable. at callUsers (/opt/iobroker/node_modules/iobroker.telegram/main.js:1262:15) at processMessage (/opt/iobroker/node_modules/iobroker.telegram/main.js:1247:21) at Adapter.<anonymous> (/opt/iobroker/node_modules/iobroker.telegram/main.js:155:17) at Adapter.emit (events.js:314:20) at change (/opt/iobroker/node_modules/iobroker.js-controller/lib/adapter.js:5634:34) at Immediate._onImmediate (/opt/iobroker/node_modules/@iobroker/db-states-redis/lib/states/statesInRedisClient.js:234:37) at processImmediate (internal/timers.js:461:21)
