Voip developer needed for Fusionpbx 4.4. 1

I have three requirements that I would like to you see if you can quote me for All are based on Fusionpbx/Freeswitch. Currently we are using Fusionpbx 4.4. 1. Develop a sticky agent feature in the call center module. [login to view URL] requirement would be Lets say a Caller has called to the system and the call was answered by Agent A and assuming the caller called within a configurable time internal (lets say 24hours) and if the Agent A is still available to take the call on that particular Queue the Caller came in , the Call needs to be routed to that agent only (Priority given to that Agent). b. If the agent is not available or busy at that moment then the call can be routed to the strategy as selected on the Call Centre Queue (Random, Idle agent etc). Please do let me know on the commercial and timeline if this can be done. 2. "Priority Queue” – enable to prioritize calls from this queue over calls from other queues the agent/extension is a member of. Example: A support team has one queue for normal support calls, and another queue for VIP customers, so even though serviced by the same agents, calls from the VIP queue get priority 3. The System must support IVR interaction capture and analysis which include: a. Capture menu failure. b. Data entry failures. c. Failure due to timeouts by the system. d. Failure due to caller hang-up. e. Frequency/popularity of IVR menu options.
