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

if its is not installed it will show “XXX “
If it is not installed then select it and click save and exit . before doing this you must check Dahdi installation .

2- Download latest version of dahdi

wget downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz
tar xvf dahdi-linux-complete-current.tar.gz
cd dahdi-linux-complete-3.1.0+3.1.0/
make clean
make
make install
make config
cd tools/
./configure
cd ..
make install-config
