Integrating Asterisk with Vtiger

I am using Vtiger subscription version.
I am new to Asterisk, I am not aware how to access asterisk server details and how to get the values of my server which helps me to integrate with Vtiger. A little help would be appreciated.

Thanks in advance.

Which version of vTiger? 7,6,5 ?

You need to configure manager.conf on asterisk first and put that credentials in Vtiger asterisk integration
