01 — Overview
How does an AI call center work alongside my existing one?
Open is not a contact-center replacement. It is a SIP-based AI voice layer that joins behind your existing platform — Five9, Genesys, NICE CXone, Talkdesk, Amazon Connect, RingCX, or in-house — as a routing destination. Calls you opt-in flow to AI; everything else runs the way it does today.
Modern call centers are typically a stack: carrier (PSTN), CCaaS or PBX (Five9, Genesys, NICE, Talkdesk, Amazon Connect, RingCX, etc.), and a layer of agents on workstations. The hard part of adding AI to that stack is not building the AI itself — it's making the AI a first-class routing destination without rebuilding the whole switchboard.
Open solves that by joining at the SIP layer. On a per-queue, per-skill, or per-IVR-branch basis, you point the routing destination at Open's SIP endpoint instead of a queue of human agents. The AI picks up, runs the conversation, calls your tools, and either resolves the call or warm-transfers it back to a human queue via SIP REFER. Your existing analytics, recording, and supervisor tooling continue to work — Open is invisible from your CCaaS dashboard except for the call legs you've routed to it.
What changes for your agents: a much smaller share of conversations reach them — only the ones the AI couldn't or shouldn't resolve. The ones that do reach them arrive pre-qualified, with a live transcript and detected intent already in the screen-pop. Average handle time on escalated calls drops because the AI has done the discovery before the human picks up.
What changes for your customers: the line is always open. There is no "all our agents are currently assisting other callers" — every call is answered on the first ring, 24/7, in the caller's language. For routine calls (status checks, password resets, appointment changes, payment captures, refunds within policy), the customer hangs up satisfied without ever queuing for a human.
Pricing is per resolved conversation, not per seat. That matters because an AI call center scales differently from a human one — you don't expand your seat count to handle a holiday spike, you just let Open absorb the load. Carrier minutes continue to be billed by your CCaaS or carrier with no markup from Open.
What stays in your CCaaS / PBX
Your CCaaS platform
Five9, Genesys, NICE CXone, Talkdesk, Amazon Connect, RingCX — your platform stays as-is.
Queues, skills, IVR, recording
Existing routing logic and recording rules continue. Open is one external destination on the branch you opt in.
Supervisor tooling and reporting
WFM, QM, CSAT surveys, and reporting in your CCaaS keep firing for the legs your agents handle.
Carrier minutes
Whoever bills minutes today continues to. Open never marks them up.
What's new with Open
A SIP destination on your queues
On the queues, skills, or IVR branches you choose, Open's SIP URI becomes the routing target.
AI handles the conversation
The AI greets, listens, runs your tools, and replies in natural speech — instead of queueing to a human.
Escalations carry context
Warm SIP REFER back to a queue with the live transcript and detected intent attached as call attributes.
Pricing model
Per resolved conversation, not per seat. Spinning up an AI on a tenth queue costs the same baseline as the first.
02 — Why it works
What makes Open the right use case answer
No-migration deployment
Joins behind your existing CCaaS / PBX as a SIP destination. The rest of your contact center keeps running unchanged.
Scales past human staffing limits
500+ concurrent calls per agent configuration. Holiday spikes and product launches stop being a staffing problem.
Resolves the routine, escalates the rest
Status checks, scheduling, payments, refunds-in-policy resolved live. Anything ambiguous or sensitive routes to a human.
Full reporting on both sides
Your CCaaS reporting on the human-handled legs. Open reasoning traces, transcripts, and outcome tags on the AI-handled legs.
03 — How it runs
What actually happens on a call
- 1
Caller hits your existing number
Routing in your CCaaS / PBX kicks in as it does today.
- 2
Selected queue / skill routes to Open
On the branches you opted in (e.g. tier-1 support overflow, after-hours, specific intents), the leg is sent to Open over SIP.
- 3
AI answers and pulls context
CRM lookup by ANI, conversation history, account status — all before the AI says hello.
- 4
AI runs the call and acts
It books, qualifies, answers, sends links, processes refunds, creates tickets — using the tools you connected.
- 5
Escalates with context
If escalation is the right call, SIP REFER hands the leg back into a CCaaS queue with the AI's transcript and intent attached.
- 6
Reporting closes the loop
Recording on both sides, reasoning trace in Open, CSAT and outcome tags exported back to your CCaaS reporting.
04 — Security
Encrypted, audited, refundable
SIP over TLS for signaling, SRTP for media. Every call logged with full reasoning traces. SOC 2 Type II, GDPR-aligned, HIPAA- and PCI-ready. Backed by the Open $2M Refund Guarantee.
