Zoho Integration with jimpisoft (Car rental and fleet management software)

Hello, we would like to integrate our car rental and fleet management software Jimpisoft with Zoho CRM so we would create a double connection mode where data that comes to Jimpisoft would be pushed to the CRM and vice versa. We need all bookings and drivers data that is on Jimpisoft to be always be synchronized on Zoho also how can we integrate our phone system and emails with Zoho as well, the phone system is based on Panasonic (PBX)
