Which Orange products are supported?

Orange Business Talk, Business Together, Orange SIP Trunking, and most Orange Business voice products. The integration pattern is SBC + SIP entity for Open behind your PBX.

Can I keep my numbers?

Yes — French and European geographic numbers stay on Orange.

What about 112 / 15 / 17 / 18?

Emergency routing stays on Orange, fully unchanged. The AI never initiates emergency calls itself.

Is this GDPR-compliant?

Yes. Open is GDPR-aligned and supports EU-region SIP endpoints so call legs and recordings stay in-region.

Yes — for any Orange SIP trunk, an SBC is the standard mediation layer.

What does this cost on top of Orange?

Orange keeps invoicing carrier minutes. Open charges per resolved conversation.

How long does setup actually take?

30–60 minutes — mostly PBX/SBC change-control.

01 — Overview

Can I add an AI phone agent to my Orange Business SIP setup?

Yes. Orange Business Talk, Business Together, and Orange SIP Trunking terminate on your SBC; Open joins as a SIP destination behind that SBC. Your Orange contract, numbers, and emergency routing stay where they are.

Orange Business remains your Tier-1 European carrier. Numbers, regulatory compliance (ARCEP, 112 / 17 / 18 / 15 emergency routing), and PSTN reach all stay with Orange. Open joins as a SIP destination on the trusted side of your SBC. The PBX you run (typically Avaya, Mitel, Cisco, 3CX, or a hosted Cloud PBX) decides which calls hand off to AI.

For inbound, the call lands on Orange, traverses the SBC into your PBX, and at the point you want AI to take over the PBX routes the call to Open's SIP entity. Orange owns the carrier leg; the PBX makes the routing decision; Open answers.

For outbound, Open opens a SIP session against the SBC using a service-account credential, and the SBC forwards to Orange. Orange-side billing sees regular outbound minutes; Open never marks them up.

What the AI does on the call: it listens, reasons over your knowledge base and connected tools, and acts. When the AI needs a human, it warm-transfers back via SIP REFER through the SBC into your PBX, which routes to a queue or skill with the live transcript attached.

Emergency routing (112, 15, 17, 18) stays on Orange. The AI does not initiate emergency calls; it warm-transfers or passes through emergency intent to your existing path.
