there is a time synchronization problem with your system, please tell your system administrator
Vicidial is having issue with time synchronization when agent is login phone is ringing and giving error as above .
In my case server time and agent machine time was showing correct.
Vicidial works on meetme application on asterisk and dahdi
1- check meet me installed and working
- go to your installation source folder mostly /usr/src/
- go to asterisk installation folder cd asterisk-13.38.1/ ” you choose your folder”
- run “make menuselect”
- check under application > Extended > app_meetme should look like below
