How We Ranked These Call Center Companies
To build this ranking we evaluated call center outsourcing providers on the criteria that actually predict program success — not headcount or brand recognition:
- Inbound & outbound delivery capability
- Agent quality, training & retention
- Security & compliance (HIPAA, SOC 2, PCI DSS)
- Technology stack (telephony, CRM, analytics, AI-assist)
- Scalability & staffing flexibility
- Service transparency & reporting
Bigger is not better in call center outsourcing. The largest providers optimize for enterprise seat counts; the best provider for most organizations is the one whose delivery model, compliance posture, and flexibility match the program being outsourced.

Choosing the Right Call Center Partner
The right call center partner is the one that fits your call volumes, hours of coverage, compliance requirements, technology, and growth plan — not the one with the most delivery centers.
Use this list as a shortlist, then compare providers through a structured request for proposal, reference checks, a security review, and a defined pilot with agreed service levels.
Global Empire Corporation builds inbound and outbound call center programs around each client's customers and operations, with the compliance depth regulated industries require.
Frequently asked questions
What does a call center outsourcing company do?
It runs some or all of your phone-based customer operations — inbound customer service, technical support, order handling, outbound sales, lead generation, and appointment setting — using its own trained agents, telephony, and management, measured against agreed service levels.
How is call center outsourcing different from BPO?
Call center outsourcing is a subset of BPO focused on live customer interactions by phone and adjacent channels. BPO more broadly also covers back-office functions like data processing, finance operations, and administration.
How should I shortlist call center companies?
Match provider specialization to your program: inbound care versus outbound sales, regulated versus unregulated industry, required languages and coverage hours, and the scale you genuinely need. Then validate with references, a security review, and a pilot.
Is a bigger call center company safer?
Not necessarily. Scale brings process maturity but also enterprise minimums and less flexibility. Mid-sized specialists routinely outperform the giants on responsiveness, program attention, and cost-to-value for anything below enterprise volume.
What service levels should a call center contract define?
At minimum: answer speed and abandonment targets, quality scores and how they are audited, first-contact resolution, escalation paths, reporting cadence, data security obligations, and exit terms including data return.
