10-Agent Call Center Setup: A Step-by-Step Guide

Step 1 — Choose your business model

The type of work decides almost everything else: technology, staffing, compliance and how you find clients. Choose one primary model for your first contract rather than trying to offer everything.

Step 2 — Decide home, remote or office

For an office, plan roughly 1.5–2.5 square metres of desk space per seat plus room for a team leader, a small training area and a server/network cabinet. Acoustics matter more than people expect: soft furnishings, desk screens and noise-cancelling headsets reduce background noise that customers hear. Check local permissions for commercial use of the premises, fire exits and employment rules for night shifts before signing a lease.

Step 3 — Design the operating model for ten seats

Ten seats does not mean ten agents on the phone every minute. Plan for leave, sickness, breaks and training (together called shrinkage — often 20–35% of paid time) and decide how many shifts you will run.

• Seats vs. headcount: at 20–30% shrinkage, keeping ten seats filled on one shift typically needs about 13–15 trained agents on payroll.
• Supervision: one team leader per 10–15 agents who coaches, monitors calls and handles escalations; at ten seats the team leader often also runs quality assurance.
• Shifts: match hours to when your client's customers can be reached or call in — and to lawful calling hours in the destination country.
• Concurrent calls: an inbound or manual-dial team needs about one channel per agent plus a few for queues and transfers. A predictive outbound dialer places more calls than there are free agents, so it may need two to four channels per agent at peak — see the SIP trunk guide.
• Skills: decide which roles need languages, product knowledge or licensing (for example regulated financial or insurance sales).
• Alternatives: if you cannot staff a full floor at first, start with five seats, or share a team leader across two small teams.

Step 4 — Build the technology stack

Details: equipment checklist, dialer and CRM guide, SIP trunk guide.

• Ten PCs or laptops, USB noise-cancelling headsets, and one spare of each.
• Business broadband with a second, independent backup connection, a business router/firewall, a managed switch and a UPS for network equipment.
• A dialer or cloud contact-center platform: hosted (subscription) or self-managed (for example VICIdial on your own server).
• A CRM or ticketing system with per-user logins, audit logs and export controls.
• A SIP trunk for outbound calls and, if you take inbound calls, DIDs (phone numbers) with IVR and queues.
• Password manager, endpoint protection, automatic updates and a backup routine.

Step 5 — Check network readiness

• Bandwidth: each concurrent G.711 call uses about 90 kbit/s in each direction including overhead; size for peak concurrent calls plus everything else on the network, with at least 30% headroom.
• Quality targets for voice: one-way latency under 150 ms, jitter under 30 ms and packet loss under 1% are widely used planning targets.
• Prioritise voice traffic (QoS) on your router, and keep large downloads and video off the agent network during shifts.
• Run a test-call plan from the actual agent PCs and network before going live — not just a speed test.
• Redundancy: a second internet connection from a different provider, automatic failover on the router, and a UPS sized to keep network gear running through short outages.

Step 6 — Set up the dialer and CRM

• Create agent logins and role-based access (agent, team leader, admin). Never share logins.
• Import leads securely: only lists you have a lawful basis to call, with suppression (do-not-call and opt-out) applied before import.
• Configure campaigns, dispositions (call outcomes), callback rules, voicemail handling and recording notices.
• Turn on audit logs and scheduled backups, and test a restore.
• Build the reports your client will ask for before the first shift, not after.

Step 7 — Inbound flow (if you take calls)

• Obtain DIDs (local, national or toll-free numbers) for each market — availability and documentation requirements vary by country.
• Design a short IVR: greeting, recording notice where required, and no more than two or three menu levels.
• Create queues by skill or language, set opening hours and an out-of-hours message or voicemail.
• Define transfer and escalation paths, and how callbacks are logged.
• Decide recording retention and who can listen to recordings.

Step 8 — Provision SIP connectivity

At CallCenterBoost every step above is reviewed by a person; there is no instant automated provisioning. See request a route test.

The realistic sequence with any wholesale carrier, including CallCenterBoost, is manual and approval-based rather than instant:

1. Request a route test for your target destinations and traffic profile.
2. The carrier reviews the intended lawful use and confirms which destinations are allowed.
3. Authentication is set up: either SIP credentials or approval of your fixed public IP address.
4. Concurrency and CPS limits are agreed for your service.
5. You place structured test calls and check answer rates, audio, caller ID and billing.
6. You fund the account using an accepted payment method, then ramp traffic gradually.
7. Ongoing: support tickets for route issues, balance monitoring and periodic re-testing.

Step 9 — Hire, train and launch

Recruit about two to three weeks before go-live, run a structured induction with compliance training, and launch with a small pilot volume before full capacity. Follow the hiring and training guide and the 30-day launch checklist.

Step 10 — Scale to 25, 50 and 100 seats

Frequently asked questions

How many agents do I need to keep ten seats filled?

Roughly 13–15 trained agents per shift at 20–30% shrinkage (leave, sickness, breaks and training). Use the staffing calculator with your own shrinkage estimate.

How many SIP channels does a 10-agent call center need?

An inbound or manual-dial team needs roughly 10–15 channels. A predictive dialer may need 20–40 at peak because it dials ahead of agent availability. Use the capacity calculator in the SIP trunk guide, then confirm with a route test.

How long does setup take?

Plan around 30 days from signing a client or committing to launch, assuming premises and internet are available. The launch checklist breaks this into weekly milestones.
