What is the difference between a call center and an answering service?

An answering service typically handles simple message-taking and basic call routing. A call center provides a broader range of services including inbound customer support, outbound lead qualification, appointment scheduling, live chat, and industry-specific intake. Estarta operates as a full call center with answering service capabilities included.

Is call center outsourcing only for large companies?

No. Call center outsourcing is increasingly popular with small and mid-size businesses because it provides enterprise-quality coverage without the cost of building an in-house team. Estarta serves businesses of all sizes with plans starting at $1,750/mo and no minimum seat requirements.

What is the difference between onshore, nearshore, and offshore outsourcing?

Onshore outsourcing uses agents in the same country as your business. Nearshore uses agents in neighboring countries with similar time zones. Offshore uses agents in distant countries (Philippines, India) for lower costs but potential language and cultural gaps. Estarta provides US-based coordination with trained English-fluent agents who understand American business culture at competitive rates starting from $1,750/mo.
