CRESTEL adds one more feather to its cap by integrating with Veraz IP Multimedia Subsystem (IMS). CRESTEL’s Provisioining Framework allows providers to set the system to extend information required for provisioning various entities. By integrating with IMS, CRESTEL ensures seamless provisioning of service plans, Reseller and customer accounts. It gives enablers the freedom to choose the information that they’d like to provision on the IMS. It enables them to control service delivery as per the different stages of customer life-cycle such as activation, deactivation, suspension and termination. On the other hand, they are able to clearly distinguish between different Resellers based on the provisioned Residential Area, Zone, Site and other physical and logical attributes, which is very essential for successfully implementing a wholesale VoIP solution.
