Background on Synergy’s Helpdesk:
Synergy has several enterprise customers that utilize this 24x7 service. We operate the helpdesk from 8am-6pm M-F. A third party technical 24x7 help desk fields the calls outside these hours. The Synergy help desk staff is on call 24x7 and is contacted first should a customer open a critical ticket outside of our normal operating hours. If our staff cannot be reached the third party will attempt to provide support outside of Synergy’s resources. This is not the goal or ideal scenario but functions as a backup should our staff become unavailable to respond to a critical ticket. There is an automated ticketing and monitoring system which is accessible to both the customer and the support agents.Synergy’s Helpdesk is NOT the first level support provided to end users. But rather, calls coming into our helpdesk are from other IT organizations. End user issues will be transferred only after they have been initially trouble shoot from the customer’s initial helpdesk team. The Synergy help desk will deal with Infrastructure issues and any issue pertaining specifically to the core infrastructure, Citrix environment including the End users sessions and published applications.
