Answer United Reviews & Testimonials
Jackie B's Review Sourced from Google
Extremely disappointing experience with Answer United. We signed up expecting a professional answering service that would follow our script, properly represent our company, and provide transcripts/recordings of calls as promised. None of that happened.Within the first weekend of service, we lost multiple jobs due to calls being handled poorly and the script not being followed. The representatives often sounded unfamiliar with our business and procedures, which reflected badly on our company.When we requested transcripts and recordings, we were told would be available; they were never provided. Customer service was also very frustrating to deal with. When I asked for a refund because the service was not delivered as agreed, I was told they had already invested time setting up the account and script. We invested employee time into that process as well, only for the agreed-upon procedures to be ignored.After bringing up these issues, communication largely stopped, and calls/emails went unanswered. Based on our experience, I would strongly recommend looking elsewhere if you want an answering service that will professionally represent your business.
Deep R's Review Sourced from Google
I used their service for a little over a year. They are very good at taking calls and usually answer them promptly. They would then pass on the message via email, though often some things in the message didn't make it across. However, if that was all I needed, then an answering machine would have been enough, I hired them as a virtual receptionist and to make appointments. Ultimately I left their service because, after more than a year they seemed to know very little about my business, they routinely had trouble answering callers' basic questions about the business. They often bungled appointment taking and I felt they were costing me business.I worked with them multiple times to change the script but still to no avail, they just didn't do a very good job as a VR.I think using them as a message-taking service is fine but would not expect anything more of them.

5 Frequently Asked Questions About Call Center Providers
What services do call centers provide?
Call centers provide comprehensive services to support customer experiences and business operations. They generally fall under 5 categories:
- Inbound call center services: Handling incoming customer inquiries and needs, including customer support, technical troubleshooting, order tracking and returns, account updates, and billing inquiries.
- Outbound call center services: Conducting customer outreach activities, such as sales calls, lead generation, customer surveys, feedback collection, and appointment setting.
- Omnichannel call center services: Managing customer interactions across multiple channels, including phone, SMS messaging, social media, live chat, and email.
- Automated call center services: Using interactive voice response (IVR), chatbots, knowledge bases, and AI-based tools to resolve routine requests and support agents.
- Virtual call center services: Providing the above services through remote or geographically distributed teams using cloud contact center platforms (CCaaS), VOIP, and workforce management tools.
Additionally, there are also specialized call centers that provide industry-specific services, such as insurance verification for healthcare and medical institutions, KYC checks for financial services, and citizen surveys for government agencies.
What is the difference between multichannel, omnichannel, and optichannel support?
Multichannel aims to reach customers through multiple channels (e.g., voice, chat, email, and social), but channels operate independently with limited shared context, which can create inconsistent customer experiences.
Omnichannel seeks to provide a consistent and continuous customer experience through all touchpoints by having a unified database and integrated system for conversation history and customer data. As a result, omnichannel strategies are often costly and require large teams to cover all customer channels.
Optichannel focuses on prioritizing and routing customers to the most effective communication channel for specific inquiries, optimizing costs rather than maximizing presence. This strategy often selects the highest customer touchpoints by analyzing customer behavior, preferences, and market trends.
How do these companies use AI?
Call center companies are using AI to improve contact center agent efficiency, service quality, and customer experience through the following:
- AI-driven self-service (e.g., conversational IVRs, chatbots, and virtual assistants) to handle end-to-end conversations and routine issues with minimal human involvement.
- AI agents assist live customer service representatives with real-time suggestions, knowledge-based answers, and automated wrap-up notes.
- Performance monitoring using speech-text analytics to evaluate agent-client interactions, flag issues, and recommend coaching actions.
- Predictive analytics to anticipate high contact volumes, staffing needs, and customer drivers (e.g., repeat contacts and churn risk).
- Intelligent call routing that uses intent detection and customer context to route inquiries to the right department or expert.
How to decide between outsourcing call centers vs. in-house call centers?
The answer depends on your support complexity, demand volatility, compliance needs, desired control, and internal team capabilities. Below is a cost-benefit analysis to help you:

When to choose offshore, onshore, or nearshore providers?
Onshore call centers operate within the same country as your business, enabling better time-zone overlap, cultural alignment, and ease of management through site visits and tighter governance. However, they often have higher costs and, in some markets, it is harder to hire at scale.
Choose onshore call center companies if you want higher control, strong brand alignment, and close collaboration with internal teams.
Nearshore call center companies are located near your country or region, making them more cost-effective than onshore and easier to collaborate with than offshore. While time zone and cultural alignment are not guaranteed, many providers build teams around your processes, language needs, and operating hours.
Choose nearshore if you want to balance cost, collaboration, and operational control.
Offshore call center providers are based in distant countries and are often selected for cost efficiency, scale, and 24/7 coverage. However, cultural and linguistic barriers, time zone compatibility, and limited quality control can be issues.
Choose offshore call center companies if you need scalable coverage, multilingual capacity, and can operate effectively with structured governance, documented workflows, and strong QA.
