Call Centers Review from Eric Martin
The salesman, Luke?, was very responsive and knowledgeable, a true professional. On boarding with Bailey, was easy and very thorough. Getting on board with an answering service had a lot more detail than I expected and Bailey was very patient and did not rush the process.

Phone Answering Services Review from Natalie Russell
Onboarding with AnswerConnect was incredibly easy. I was able to schedule a virtual meeting right away, and within an hour we had everything set upportal access, hours of operation, and customized scripting.
Since getting started, Ive received positive feedback from both clients and prospects about the agents handling my calls. That alone speaks volumes.
A few weeks in, I decided to tweak my scripting to improve the flow and be more transparent with callers. I reached out via chat, and their team responded immediately. They even offered to call me to walk through the changes, which I appreciated. We updated everything in real time, and the process was seamless.
Super friendly team, quick to respond, and very easy to work with. Overall, a very positive experience with AnswerConnect.

Johnson Legal PLLC
Review from Google

Johnson Legal PLLC's Review Sourced from Google
As a small law office, we used AnswerFirst for about a year. We opted not to have calls recorded as their system has an irritating "beep" that sounds in the background while customers are on the phone. We thought things were going well. Several months later we signed up for CallRail, which recorded all incoming calls. We began to see a pattern of poorly handled calls. When we shared this information with management, and offered to provide the recording, they said "no thanks." The probems continued. For instance one caller asked if we did simple Wills. The AnswerFirst agent said, "No, we only do Estate Planning." After sharing these simple issues with management nothing changed. We asked if they could give us an adjustment to our bill based on the poorly handled responses. They said "No." We notified them this week we were switching carriers and they acted like they could care less. DO NOT use them as they cannot handle the simplest of calls.

Outstanding After-Hours Answering Service – Highly Recommend for Service-Based Businesses
We've transitioned to AnswerFirst about four months ago for our after-hours answering service needs, and they’ve exceeded every expectation. Their live agent support, combined with responsive customer service and advanced technology integration, has provided our team with a seamless and professional solution that far surpasses our previous provider.
What sets AnswerFirst apart is their adaptability to our unique workflows, quick response times, and overall attention to detail. As a service business, having a reliable, U.S.-based call center is essential and AnswerFirst delivers with consistency and clarity.
Their platform gives us the functionality we need, and the quality of their after-hours call handling has significantly improved both our internal efficiency and our customer experience.
If you're a service-based company looking for high-quality live agents, professional support, and a partner who understands urgency and accountability, I highly recommend AnswerFirst. Exceptional value, exceptional team.

Jeff Short's Review Sourced from Google
Very inconsistent on the quality of calls answered and the quality seems to be decreasing. We lost quite a few potential customers in the last week due to "robotic" and emotionless agents who sound like they have no interest in doing their job. When you call in to discuss your business relationship, you find out your relationship manager is whomever answers the phone. Be prepared to discuss everything you expected and implemented when you were sold the plan all over again.

Jeff Tate's Review Sourced from Google
I would not recommend them unless you like paying for extra services over what it stated in your agreement. I found out they have deviated from my approved template for a long time. They did not have a good reason for why. I am paying $2 a minute for a call agent to ask additional questions over what I have approved. I think we all know why the additional question are being asked. I asked for a credit on my bills since I paid for the additional minutes and surprise!!!, I never heard back from them.

5 Frequently Asked Questions About Telemarketing Firms
What do telemarketing companies do?
Telemarketing agencies use phone-based direct marketing to sell products, generate leads, or book appointments on behalf of businesses, performing both outbound and inbound calls to grow sales pipelines and client relationships.
As all telemarketing interactions involve direct human contact, the approach allows them to influence potential customers’ opinions, purchasing habits, or perceptions toward a brand.
What services do telemarketing firms provide?
Telemarketing services for businesses can be split into two main categories: inbound and outbound.
Inbound telemarketing services cover customer support calls, namely technical support, order taking, billing inquiries, upselling, and virtual receptionist service, to name a few. They can support both B2B and B2C companies.
Outbound telemarketing services, also referred to as proactive outreach, are intended to boost businesses’ bottom line. This category comprises several different service types, including lead qualification, appointment setting, cold calling, customer reactivation, and more.
B2B telemarketing companies are often hired to assist non-profit organizations in soliciting donations or to collect debt and follow up on overdue accounts on behalf of other businesses.
How much do telemarketing agencies charge for their services?
Telemarketing agencies charge between $7 and $75 per hour for their services. The service cost can also vary based on location (offshore vs. onshore), campaign complexity, duration, and agent experience, with B2B telemarketing campaigns often costing more than B2C.
Other common pricing models include:
Per-lead: $35 to $60 per qualified lead
Flat-rate: $650+ for a 4-week campaign
Commission-based: 5% to 20% of each closed sale
How long do telemarketing campaigns take?
Telemarketing campaigns usually take a few months, as lead nurturing takes multiple phone calls for telemarketers to engage with a prospect and close a sale.
Although initial lead generation begins within the first few weeks, for a full, effective cycle, the campaigns are run between 3 and 6 months. The average campaign takes about 14 weeks to reach an optimum level of opportunities per day. The length also depends on the campaign type:
Pilot and trial campaigns: Usually run for 10 to 12 weeks to test the market, refine the pitch, and validate traction.
Short campaigns: 4 to 6 weeks for time-sensitive promotions or event registrations.
Long-term campaigns: 6 months to over a year for slow B2B sales cycles that require more lead nurturing.
What kind of ROI can businesses expect from telemarketing campaigns?
Lucrative telemarketing campaigns often result in a 5:1 to 10:1 return on investment (ROI), meaning $5 to $10 in revenue for every $1 spent. The return rate depends on the quality of the call lists, the persuasion skill of the callers, the product, the offer, and whether it's part of a multi-channel strategy. Notably, ROI grows over time through stronger customer retention and better targeting informed by feedback from calls.
