    I need someone to modify the call center module of elastix.We are running an outbound call center and generate many calls per day.The elastix Call center module is great for us but there is one drawback that we need to get fixed.We are looking for an asterisk/elastix experienced programmer to modify the script.Here is the problem we are looking to fix:Whenever a call is placed and ended, the agent on the call do not have enough time to enter any notes or disposition or any other details of the call. We would like to add a delay between each call so once the customer hangs up, the agent is still "in call" and once he save the form information , he will be available to receive calls again. it seems this needs to be modified within the script.If all goes well we have a few other modifications we would like to implement.Please only message me if you have asterisk or elastix.
