Operator Connect Rebiller - Partner Support Requirements 

CallTower requires that its Operator Connect Rebiller Partners provide first level support for their customers. 



This article will outline the required support that is to be provided by an Operator Connect Rebiller Partner.

  • Manage all communication with the customer 

  • Provide initial support for installation and configuration needs 

  • Provide detailed information about the issue and the troubleshooting performed.

  • Verify licensing 

  • Restarted the device 

  • Cleared the Microsoft Teams cache
