Connect Your Jamaican Number to Any AI Receptionist with WOCOM: OpenAI, ElevenLabs, Vapi, Retell and More

AI receptionists have moved from demos to real phone lines. Platforms like OpenAI, ElevenLabs, Vapi and Retell can answer a call, understand the caller, answer questions, book appointments and pass the call to a person. For a Jamaica business there is one catch: none of them sells Jamaican phone numbers. Their own numbers are mostly US, Canadian or European.

The answer is SIP, the standard that business phone systems use to carry calls over the internet. Every major voice AI platform accepts calls over SIP. WOCOM, as a licensed Jamaican carrier, can take a call to your +1-876 or +1-658 number and deliver it to the platform you choose. Your customers keep dialling the number they already know.

How It Works

1. A customer dials your Jamaican number from any local or international network.
2. The call arrives on the WOCOM network, exactly as it does today.
3. WOCOM forwards it over SIP to the AI platform's address.
4. The AI answers, talks with the caller and, when needed, hands the call back to WOCOM to ring a person: an extension, a ring group or a mobile.

Outbound works the same way in reverse: the platform sends the call to WOCOM with credentials we issue, and the person you call sees your Jamaican number.

The Platforms, and a Guide for Each

We have written a step-by-step guide for each of the main platforms, checked against each vendor's own documentation in November 2026:

• OpenAI (Realtime API and GPT-Live): OpenAI's speech-to-speech models answering calls directly. Built for developers; requires TLS and SRTP. Read the OpenAI guide.
• ElevenLabs Agents: very natural voices, a dashboard import for your number, and a choice of GPT, Claude or Gemini underneath. Read the ElevenLabs guide.
• Vapi: a developer platform where you pick the model, voice and carrier separately. Read the Vapi guide.
• Retell AI: a builder with good testing tools and a one-click SIP connection test. Read the Retell guide.
• Synthflow: no-code flows; SIP connection is Enterprise-only and uses unusual ports. Read the Synthflow guide.
• Bland AI: high-volume calling; TLS-only SIP. Read the Bland guide.
• Ultravox: a speech-native model with SIP built in. Read the Ultravox guide.
• LiveKit Agents: the open-source framework, on LiveKit Cloud or your own servers. Read the LiveKit guide.
• Pipecat with Daily: an open-source Python framework with Daily's SIP dial-in. Read the Pipecat guide.

What about Anthropic's Claude and Google's Gemini? They are language models rather than phone platforms. You use them inside one of the platforms above, and our guide to choosing the model explains how.

What WOCOM Needs from You

Whichever platform you choose, the WOCOM side is the same short conversation. Tell us:

• The number(s) to connect, in E.164 form: +1876XXXXXXX.
• The platform's SIP address, port and transport (UDP, TCP or TLS). Each guide shows where to find it.
• Whether the AI needs to place outbound calls.
• Where transferred calls should go.
• Whether you need encrypted calling (TLS signalling and SRTP audio). OpenAI and Bland require it.

We set up the route, give you any credentials and addresses the platform asks for, and test a call with you.

Things to Decide Up Front

All calls, or only some?

You do not have to give the whole line to an AI. Common set-ups are: AI after hours only; AI when the front desk does not pick up within a few rings; AI on a campaign or overflow number; or a menu option such as “press 3 to book an appointment”. Your WOCOM Cloud PBX time conditions and ring groups handle all of these.

What happens when the AI fails?

Platforms have outages. Ask WOCOM to set a fallback so that if the platform does not answer, the call rings your team or goes to voicemail instead of failing.

Who owns the data?

Recordings and transcripts of calls the AI handles are stored by the platform you choose, under its terms. Read its data and retention policy, and tell callers they are speaking with an automated assistant. Jamaica's Data Protection Act applies to how you use that information.

Quality Tips for Jamaican Callers

• Use wideband audio where you can. WOCOM supports G.722 HD. Platforms that accept it (ElevenLabs, Retell, LiveKit, Ultravox, Bland) hear the caller more clearly, which helps with names and addresses.
• Teach the agent local words. Parish and community names, street names and your product names belong in the agent's instructions or vocabulary.
• Test with real voices. Have staff from different parishes call in, on mobile and on landline, and listen to the recordings.

Our go-live checklist covers testing in detail, and the comparison helps you choose.

Or Use the One Built In

Every platform above is a build-it-yourself project: someone has to write the prompts, connect the calendar, and keep it up to date. If you want an AI receptionist that already understands Jamaican callers, knows your business hours, takes messages, transfers calls and emails you a summary, WOCOM AI is included with Cloud PBX. Many businesses run WOCOM AI on the main line and experiment with another platform on a second number.

Either way, the number stays yours and the call stays on a Jamaican network. Contact WOCOM to connect your first line.
