Need help with Vtiger, Owncloud and Elastix Campaigns

Hello! i have a customer who recently got hacked his Elastix PBX so he need us to develop the task to make it to run again, then while i will be checking the elastix contexts, routes and the core PBX to check if everything it is ok the customer wants also other tasks to be performed like: 1.- Make the Vtiger CRM to run again (apparently it is offline) then needed to be running and up (consider maybe the customer can ask extra things of the CRM like how to use it or things like that) 2.- Make the Owncloud to run again, apparently it is offline and they want it to run (i dont know for what they are using it) 3.- Help the Elastix to run again the callcenter campaigns (maybe we need to make one for testing purposes or something then consider it also)
