Configuration sugarcrm + freepbx

I have the following questions
In step 04 -
“Configuring SugarCRM data connection (you need url, username and password for this) The usename and password are required for safety reasons so that only a registered user can access SugarCRM module. This section should perhaps be included in Elastix links.”

What URL place?
Which username? of the login sugarcrm?

thank you

yes they are sugarcrm related url,user and password for authentication
