Call Center Outsourcing: Everything You Need to Know

Most growing businesses reach the same milestone at some point: customer requests start arriving faster than the internal team can answer them. Hold times creep up, after-hours calls go to voicemail, and people who should be focused on product or sales end up covering the phones.

This is where contact or call center outsourcing can help. Today, though, outsourcing is one of several ways to add capacity rather than the only one. Teams can grow with in-house agents, an outsourcing partner, AI agents that handle routine requests, or a mix of all three.

Let's look at what call center outsourcing is, how it works, what it typically costs, the trade-offs to plan for, and where AI fits into the decision.

What is contact or call center outsourcing?

Simply put, call center outsourcing involves contracting a team of agents that work outside of your company to handle customer conversations on your behalf. The outsourcing partner, often a business process outsourcing (BPO) provider, recruits and manages the agents, while your business sets the standards, processes, and goals they work toward.

Outsourced teams can handle customer service, help desk and technical support, sales, appointment setting, and billing questions across phone and digital channels like chat, email, and social media.

Common call center outsourcing models

Outsourcing arrangements usually differ along three lines:

• Inbound vs. outbound: An inbound call center typically focuses on customer service and support. An outbound call center typically focuses on sales, lead generation, and follow-ups. You can outsource either or both.

• Onshore, nearshore, or offshore: Domestic (onshore) outsourcing keeps agents in your own country, which can simplify time zone and language alignment. Nearshore partners operate in neighboring countries, and offshore partners operate farther away, often at lower labor costs but with more coordination across time zones.

• Dedicated vs. shared agents: Dedicated agents work only on your account and build deeper product knowledge. Shared agents split time across several clients, which can lower costs for smaller or less predictable volumes.

How call center outsourcing works

Most outsourcing engagements follow a similar path:

1. Define the scope: Decide which channels, request types, hours, and languages the partner will cover.

2. Choose a partner: Compare providers on industry experience, location, security practices, and the technology they use.

3. Transfer knowledge: Share product information, policies, escalation paths, and your brand voice so agents can represent your business accurately.

4. Set service levels: Agree on metrics like average handle time, answer speed, resolution rate, and customer satisfaction, and write them into the service level agreement (SLA).

5. Manage and review: Monitor performance, review calls, and update training as your products and policies change.

How much does it cost to outsource a call center?

Call center outsourcing costs vary widely based on where agents are located, which channels they cover, how complex the requests are, how many languages you need, and whether coverage runs around the clock. Providers commonly price engagements in one of four ways:

• Per hour: You pay for each hour an agent is staffed on your account.

• Per minute: You pay for time agents spend actively handling conversations.

• Per contact: You pay a set rate for each call, chat, or email handled.

• Per outcome: You pay for results, such as a booked appointment or a completed sale, which is more common for outbound work.

Many contracts also include setup and training fees. When you compare quotes, factor in the internal time your team will spend managing the partner, reviewing quality, and connecting the partner's systems to yours.

Benefits of outsourced call centers

The benefits of call center outsourcing usually come down to flexibility: you get access to trained agents, coverage, and skills without building all of it yourself.

1. More flexible costs

An in-house team carries fixed costs for recruiting, training, salaries, benefits, and workspace. Outsourcing can turn much of that into a variable cost that rises and falls with your volume, freeing capital for other priorities.

2. Coverage across time zones and peak periods

Outsourcing partners can staff evenings, weekends, and holidays, and add agents quickly during seasonal spikes or product launches. That can improve answer times without hiring for your busiest week of the year.

3. Specialized skills and languages

Some partners specialize in industries like healthcare or financial services, or offer agents who speak the languages your customers use. If your in-house team doesn't have those skills yet, a partner can potentially provide them faster than you could hire.

4. More focus for your internal team

When a partner handles routine or overflow volume, your in-house team can concentrate on complex issues, high-value customers, and the work your business specializes in, which can also help with customer retention.

Risks and trade-offs to plan for

Outsourcing can work well, but it changes how much of the customer experience you control directly. These are the areas to address in your contract and management plan before launch:

• Less direct control: You won't manage outsourced agents day to day, so quality depends on clear standards, regular reviews, and visibility into live and recorded conversations.

• Consistency across teams: When in-house and outsourced agents handle the same customers, differences in training or tone can show up quickly. Shared processes and shared tools help keep the experience consistent.

• Data security and compliance: A partner will handle customer data on your behalf. Confirm how they protect it, who can access it, and how they meet the regulatory requirements that apply to your industry.

• Knowledge transfer: Product details, policies, and edge cases need to reach the partner and stay current as they change.

• Brand voice: Customers see one company, not two. Agents need to sound like your business, which takes onboarding, example calls, and ongoing coaching.

What you can outsource

You can outsource an entire department or a single slice of your volume. Common options include:

• Inbound customer service: General questions, account changes, order issues, and returns.

• Outbound sales and lead generation: Prospecting, outbound lead generation, appointment setting, and follow-ups, often priced per outcome.

• Technical support: Troubleshooting and help desk support, where specialized partners may already have trained agents and tooling in place.

• After-hours and overflow coverage: Evenings, weekends, and spikes your in-house team can't absorb.

Outsourcing partners rely on the same kinds of tools in-house teams do. MarketStar, a global sales and marketing outsourcing company, uses Dialpad Sell, Dialpad's outbound contact center solution, to run outbound sales teams for its clients. Its reps use AI Live Coach Cards that surface talking points during live calls, which has helped MarketStar shorten ramp time for new reps.

"We are building much more efficient and scalable sales teams for our clients with the help of Dialpad Sell. Historically, onboarding new sales reps has been time and resource intensive. Since implementing Dialpad Sell, we've been able to ramp employees quicker, get them on prospect calls sooner and produce enhanced results for our clients."

Outsourcing, AI agents, or both?

AI agents have added a new option to the in-house vs. outsource decision. Instead of choosing only between hiring more people and contracting more people, many teams now start by asking which conversations need a person at all.

What AI agents handle well

AI agents work best on routine, high-volume requests with a clear outcome, such as order status, appointment scheduling, account updates, and identity verification. Because they don't need shifts, they can also cover after-hours requests and absorb sudden spikes in volume. And since they answer from the knowledge and systems you connect, responses stay consistent from one conversation to the next.

What outsourced human teams handle well

Outsourced agents are a better fit for conversations that call for judgment or empathy, such as complaints, billing disputes, and exceptions to policy. They can also bring specialized expertise, broad language coverage, and the persistence that high-touch outbound sales often requires.

How the options compare

A hybrid model

For many teams, the answer is a mix. AI agents take routine first contact, your in-house team handles priority customers and complex issues, and an outsourcing partner covers overflow, after-hours, or specialty queues. What makes this work is the handoff: when a conversation moves from an AI agent to a person, whether in-house or outsourced, the context should move with it.

It also helps to size an outsourcing contract around the volume that actually needs people. In Dialpad, Skill Mining analyzes human-to-human contact center calls and recommends AI agent skills based on the share of calls each one could handle, so you can see how much of your volume could be automated before you decide how much to outsource. With Dialpad AI Agents, escalations pass the transcript and context to the human agent who picks up the conversation, so customers don't have to repeat themselves.

How to decide what to outsource

There's no single right mix. These questions can help you decide which work stays in-house, which goes to a partner, and which an AI agent can take on:

• How predictable is your volume? Steady volume can justify in-house hiring. Seasonal or unpredictable spikes may favor a partner, AI agents, or both.

• How complex are the requests? Structured requests are strong candidates for automation. Requests that need judgment or deep product knowledge may need your own team.

• What compliance requirements apply? Regulated industries need to confirm how any partner or AI vendor handles customer data before handing over conversations.

• How much control do you need? The closer a conversation is to revenue or retention, the more direct oversight you'll likely want.

• What does your budget and timeline look like? Outsourcing and AI agents can add capacity faster than hiring, but each comes with its own setup and management time.

• What do your customers expect? Some customers are happy to self-serve. Others expect to reach a person quickly, and your mix should reflect that.

Best practices for managing an outsourced contact center

Once you've decided what to outsource, the way you manage the partnership determines whether customers notice the difference.

1. Run every team on one platform

When in-house agents, outsourced agents, and AI agents work in the same contact center platform, routing, reporting, and customer context are shared rather than split across tools. Managers can compare performance side by side, and customers get the same experience no matter who answers.

PadSplit, a housing marketplace, manages an outsourced contact center team in the Philippines from its US headquarters on Dialpad's platform. Its team uses reporting to track how the outsourced team performs alongside the domestic team, and supervisors use live transcripts and sentiment analysis to see when a call needs attention. Agents in both locations can also shadow each other's calls for training.

2. Document processes and workflows

Clear process documentation, escalation paths, and decision trees help agents choose the right next step, keep errors to a minimum, and make updates easier to roll out across every location.

3. Keep priority issues in-house

Use call routing rules to decide which conversations go where. For example, you might route high-value accounts and escalations to your domestic team, send common questions to an outsourced partner, and let AI agents handle routine requests first.

4. Monitor quality across teams

Quality monitoring matters more when you don't sit next to the agents. In Dialpad Support for contact centers, supervisors can view live calls with real-time transcripts, sentiment, and detected call purpose, then listen in, whisper to the agent, barge in, or take over the call when needed. After the call, AI Scorecards and contact center analytics help managers review performance consistently across in-house and outsourced teams, and AI Live Coach can surface guidance to agents during live conversations.

Choosing the right mix for your customers

Whether you outsource an entire department, part of your volume, or start with AI agents for routine requests, the goal stays the same: customers shouldn't be able to tell where one team ends and the next begins. That depends on shared processes, shared context, and clear visibility into how every conversation is going.
