Regal is an AI contact center platform for enterprises of 25+ agents, with phone, SMS, chat and web voice AI agents alongside human agents, priced by quote. Five9 and Synthflow are alternatives for enterprise contact centers. SalesCloser does a different job: your AI sales team talks to buyers on the phone and your website by chat, voice and video, runs live demos and books or transfers the ready ones to your team.
Regal builds AI voice agents for enterprise contact centers, running alongside human agents on one platform for phone, SMS, chat and web voice. Teams looking for an alternative usually want one of two things: a different enterprise contact center platform, or an AI sales team that fits a smaller sales operation and also works on the website and runs product demos.
Here is what Regal offers, the main alternatives, and where SalesCloser fits. Competitor details come from each vendor’s own website, checked in November 2026.
What Regal offers
Regal lists phone, SMS, chat and WebRTC voice AI agents, an agent builder and Regal Copilot, a unified customer profile, a journey builder, IVR, A/B testing and simulations, conversation intelligence, a sales dialer, monitoring and analytics, plus a unified desktop for human agents. Its use cases are lead qualification, appointment setting, collections, bookings and customer support, with versions for insurance, lending, banking, healthcare, education, legal and local services.
Regal says it works with enterprise companies, and its FAQ gives a guide of at least 25 agents and 100,000 call minutes a month. Pricing is by quote: you pay for the features you use, with discounts for higher spend and longer contracts.

Where SalesCloser is different
Regal is built to run an enterprise contact center with AI and human agents side by side. SalesCloser is your AI sales team: agents that talk to new buyers, qualify them, show the product and book the next step with your team, without contact center scale.
- It fits a sales team, not just a contact center. You build and change the agent yourself, for the sales conversations your team has today.
- It works on your website too. A website agent talks to visitors by chat, voice or video, so buyers who never call still get a conversation.
- It runs the demo. In a web video call or on Zoom, a demo agent shows your product by live screen share or video.
- It answers and calls. Phone agents take calls to your sales line 24/7, and outbound campaigns call your list inside your calling hours.
What that looks like: a mortgage broker with six loan officers gets web leads and calls from homebuyers comparing rates. The phone agent asks about the purchase price, down payment and timeline, explains the next steps in getting pre-approved, and books a call with a loan officer. Web visitors ask the website agent the same questions by voice. The broker gets a booked calendar without running a contact center.
