About Call24: Review and comparison

Call24 Communications is a privately-owned, family-operated company that provides outsourced call center services to California clients. The company has been in business for more than 30 years. 

Call24 agents act as an extension of their client’s business. This allows clients to receive unique and personalized experiences, unlike any other outsourcing agency. 

This company’s main focus is on providing the highest quality call center services possible without breaking the bank. It does so through its leading-edge technology and highly skilled employees. 

According to LinkedIn, this company has an estimated 51 to 200 current employees. These employees undergo a minimum of three weeks of supervised training to perfect their customer service skills to ensure that clients receive nothing less than the best experience possible.

Call24 Outsourcing

Call24’s headquarters office is in Pleasant Hill, California. The company currently only services clients in California, but it operates in many cities, including San Francisco, Oakland, and Walnut Creek. 

The company offers 24/7, around-the-clock service 365 days a year. It has various backup plans to ensure that service stays uninterrupted, such as battery-powered generators and phone lines. 

Call24 was founded in 1977 and has been a family-owned and operated business since.

Call24’s BPO services and pricings

Call24 offers various 24/7 full-service call center services to its Californian customers. The company customizes its services to meet its clients’ specific needs. Some of the particular services that the company offers include:

  • Inbound and outbound calling
  • Email management
  • SMS messaging
  • Order taking
  • Appointment scheduling
  • Schedule management
  • Urgent dispatch
  • Voicemail
  • Legal answering
  • After-hours answering
  • Virtual receptionist

Call24 pricing

Call24 recognizes the importance of providing high-quality answering services and customer service at affordable prices. The company guarantees that its services will cost less than the price of hiring a full-time representative. 

The company doesn’t offer any further information regarding the cost of services on its website, but you can fill out a free contact form to get in touch with a representative to further discuss service prices.

How Call24 outshines its competition

Call24 provides some of the top outsourced call center services in California. With the company’s top-of-the-line, leading-edge technology, it’s able to provide around-the-clock service to its dozens of clients. 

Unlike many similar-sized companies in the United States, Call24 requires that its employees undergo rigorous and ongoing training to help ensure service excellence. It takes a minimum of three weeks for an employee to start taking calls on their own, and employees are retrained as technology and client needs advance.

Call24 reviews and comparisons

Call24 works hard to provide the highest quality call center and virtual receptionist services possible. We were unable to find any verified reviews from employees at Call24, but we suspect that the company and work environment are comparable to other midsize Californian call centers.
