What Is Call Center Outsourcing?
Call center outsourcing is the practice of contracting an external provider to handle a company’s inbound and outbound customer calls, plus email and chat support, under agreed service levels. An outsourced call center is the external team of agents, supervisors, and systems that handles those customer interactions on the company’s behalf.

How Does Call Center Outsourcing Work?
Call center outsourcing works by agreeing on scope and service levels, transferring call handling to a trained external team, and reviewing performance against agreed KPIs. The steps of call center outsourcing are listed below.
- The company defines the scope of work and the service level agreement (SLA), including call types, hours, and targets.
- The provider hires and trains agents on the company’s products, policies, and brand voice.
- The agents handle customer calls using the company’s systems or the provider’s platform.
- The provider reports KPIs such as service level, resolution rate, and customer satisfaction.
- The company and the provider hold regular reviews to adjust scripts, staffing, and targets.

The 5 call center outsourcing models are listed below.
- Onshore: Onshore outsourcing uses agents in the company’s own country, which gives the best language and culture fit at the highest cost.
- Nearshore: Nearshore outsourcing uses agents in a nearby country, which balances moderate savings with close time-zone alignment.
- Offshore: Offshore outsourcing uses agents in a distant country, which gives the largest labor savings but needs closer management across time zones.
- Dedicated Agents: Dedicated agents work only on one company’s account, which suits steady, high call volumes.
- Shared Agents: Shared agents split their time across several client accounts, which suits lower or unpredictable call volumes.

- Check the provider’s experience in the company’s industry.
- Confirm data security certifications such as PCI DSS for payments and SOC 2 for data controls.
