		Related Products Numa Dealerships don't lose customers because of price. They lose them because the phone rings and nobody answers, the customer calls three times for one status update, and the manager finds out about a problem when the survey comes back. Numa is the AI Operating System that fixes this where it breaks: in the daily work. Operator answers and routes every inbound call, so nothing goes dark. Status Updates reaches the customer before they have to call, so advisors stop drowning in callbacks. Voice AI books the appointment in the conversation, so the customer never waits. LiveCSI™ flags upset customers in real time, so managers step in before the CSI score takes the hit. Opportunities goes after declined services, open recalls, and equity moments while they're still warm. One inbox. One shared context. Your whole team working from the same system. Surveys tell you what happened last month. Numa is what happens today. 14 Ratings Visit Website Bigly Sales Bigly Sales is a fully managed AI outbound calling platform designed for revenue teams that want to automate lead outreach while centralizing compliance, telephony infrastructure, and CRM integration.

	Pros & Cons from Real Users Pros Love this Auto Dialer product. Features are extremely easy to use and are a must for any small to medium enterprise that needs to gain better traction making phone calls. Easy to upload contacts and build simple campaigns. Easy to add teams and manage team member. Pricing is great. Cons Support isn't fantastic. Calls come at crazy times of the day and night. Support doesn't respond very quickly and required nearly one week to get the trial going.
