Vtiger 7 CRM "Click to call" and and PBX recordings integration

I have Vtiger 7 CRM, previously we had to use asterisk PBX installation for the specific setup but due to the inactive time period of the business, existing PBX settings are no longer exist. we did install issabel Asterix into another centos machine. since we already have all installations for both issabel Asterix and vtiger, and they are both in working conditions and vtiger already has the related module for its own... it should to be taken only 1 hour for a guy who has previous experience on the task... (both voip calls and vtiger are in working condition) What I want: -CRM Users should able to use "click to call" dialing options for making outgoing calls right from Vtiger CRM by clicking on the numbers. -Instant pop-up alerts for incoming calls displaying the contact/leed name if it exists in CRM otherwise; it should create a new leed card in front of the salesperson -Vtiger Asterisk Integration logs for both incoming and outgoing calls. -Completed conversation history in the PBX manager page should allow the salesperson to click and listen to the past calls -Able to access past calls inside the PBX Manager module. what will be provided to you: -both İssabel and vtiger root access with ssh and also vtiger side will have FTP user and also if needed remote desktop access. -Admin management passwords for issabel Asterix and vtiger -phpmyadmin password for vtiger -mysql password for vtiger -remote assessing will be allowed over on port forwarding settings for your public IP -live support will be provided during the whole task Happy bidding.
