IN SHORT
What is an AI service center?
An AI service center is a Voice and Video Agent that handles a business’s conversations on every channel at any hour: it answers and places calls, video calls, texts, emails, WhatsApp and chat messages, resolves routine requests under the policies the business sets, routes emergencies and judgment calls to a person with a summary, and keeps the team informed in Slack, Teams or Google Chat. Sentinel Service Center does this under your brand, with the Voice Agent on every call.

SERVICE CENTER · VIDEO
See the problem.
Fix it on the call.
A recorded call, not a script. When a caller shows the problem on camera, the Video Agent reads what it sees and works through it with them, so many requests never need a visit.
HOW A CALL RUNS
Answered, understood,
resolved, recorded.
Only people can build trust. Only people can show empathy. Only people can calm an angry customer. Only people can make difficult decisions. Everything else? Let Sentinel handle it.

SERVICE CENTER · AFTER HOURS
What happens when
nobody picks up.

QUESTIONS
What teams ask about the Service Center.
Something else? Ask Sentinel directly, or pick your industry for answers specific to it.
The communication layer for your operation: AI Voice and Video Agents on every channel, inbound, outbound and internal. They answer and place calls, texts, emails, video calls, WhatsApp and chat messages, resolve what they can under your policies and hand the rest to the right person with a summary. The Voice Agent is its voice channel.
An answering service takes a message. Sentinel resolves the request: it books, answers, checks status, collects details and follows up, and only involves your team when a decision is needed.
Across customers, 75.1% of calls are resolved without a person stepping in. The rest reach your team with a transcript and a summary, not a voicemail.
Externally: voice, video with voice, SMS, email, WhatsApp, live chat and the web. Internally: Slack, Microsoft Teams and Google Chat. You choose per client, site or request type, so video can stay off at sites that don’t allow recording.
Yes. The Voice Agent is private-labeled as your technology and trained on your policies, emergency protocols and escalation contacts. Callers hear your name, not ours.
About 50¢ for a three-minute call, against roughly $3,000 a month to hire someone to answer the phone. We run the numbers with your call volumes in a walkthrough.
With basic location and contact information, as soon as tomorrow. Forward all calls, overflow only or after hours only; your numbers stay the same.
Requests reach your team as formatted emails your system accepts from day one. Direct integration comes once you are ready.
