Top outbound call centers: 2024 Services & solutions

Outsourcing is the leading sector in the global market industry. Organizations of all types and sizes worldwide have become an essential part of their business strategies as it aids in their overall progression.

In the US alone, companies farm out over 300,000 job functions for the sole purpose of cost reduction. A considerable portion of the outsourcing practice globally is perhaps in the call center sector.

In previous years, call centers have been very controversial for various businesses. Frustrated and angry callers would usually wait in long queues for a long time.

In worse cases, they end up not resolving issues or getting answers to their questions.

A lot of these organizations lack proper management, skills, workforce, and resources. These reasons urged companies to outsource to top outbound call center companies, as well as inbound call centers outsourcing companies.

Excellent customer experience is the primary goal in call center functions. Companies can maintain and nurture a good relationship with their customer base through call centers.

Thus, every entrepreneur knows well enough that they can’t earn profit without customers. Without proper revenue, their business will eventually nosedive.

While call centers are vital to every business, setting them up is not easy. Establishing an entire call center infrastructure alone needs enough budget, planning, and time. Not to mention, a good volume of call center agents is required to make it fully functional.

Fortunately, more organizations have recognized the wonders of outsourcing call centers. This outsourcing sector has been steadily growing throughout the years.

According to recent research statistics, the global call center outsourcing market can reach over $27.64 billion. It is also estimated to have a compound annual growth rate (CAGR) of 4.8% for 2022-2027.

Inbound and outbound call center: A quick comparison

Generally speaking, call centers are either inbound or outbound call centers. While these two classifications involve voice calls, they both have their significant differences:

Inbound call center 

An inbound call center is when the call center agents receive incoming calls from the customers. Customers commonly phone in for customer service. Specifically for technical support, appointment setting, order processing, and inquiries.

Outbound call center

Leading inbound and outbound offshore call center destinations

Thriving companies can save more on their overall costs while tapping into global talents through offshoring. Over the past few years, the Philippines and India are two powerhouses in offshoring as a whole.

And as for offshoring call centers, below we have outlined three of the leading countries where most foreign companies delegate this job function:


The Business Process Outsourcing (BPO) industry in the Philippines started with call center outsourcing. Even to this day, call centers consist a vast portion of the outsourcing services in the country.

As a developing country, foreign companies can massively save on costs as they offshore their inbound and outbound call centers in the region. Moreover, the Philippines has a very high literacy rate, and a big part of the Filipino population is proficient in speaking the English language.

Western culture also heavily influences the country, making it easier for locals to converse and understand westerners. Filipinos also have neutral accents, which is advantageous as they can learn and adapt to different accents faster.


India has flexible government outsourcing policies making it favorable for foreign organizations to offshore their inbound and outbound call centers. The country also has well-skilled English-speaking workers and exceptional communication networks.

Similar to the Philippines, India also has a relatively cheaper wage rate than foreign companies keeping their call centers in-house. Apart from call centers, India also has been famous for IT-related BPO services.
