Empty caller log CTI integration


  • Used Zammad version: 3.3
  • Used Zammad installation source: deb package
  • Operating system: ubuntu server 18.04
  • Browser + version: firefox 79.0

Expected behavior:

  • Caller log shoould be populated

Actual behavior:

  • Caller log is empty

Steps to reproduce the behavior:

  • Caller log used to be populated,
    We had to change system time with the timedatectl command to different UTC after we noticed sequential entries in production.log with hours gap between them.
    entry 1: 12:06
    entry 2: 15:06
    entry 3: 12:06

After we issued the timedatectl command and a reboot all caller logs entries disappeared and no new entries are created since then even though we can see http calls under
Integrations -> CTI -> recent logs.

Are there any errors in your production log?

Can you please tun the following commands in the zammad rails console and provide the outputs here?


Thank you

Hey MrGeneration,

Here is the console output:


Seems like it is a timezone issue as suspected?

As for production log, all the errors are pretty much the same and seems like my SIP provider sending empty parameters on some answer and hangup events:

Thank you
