Add a live interpreter to a 3CX call

1
Get your TalkTool number and org code
Sign up for TalkTool to receive your conference-in phone number and a short organization code. Keep both somewhere your 3CX agents can reach quickly — a speed dial, a shared note, or a saved contact in the 3CX phonebook.
- Add the TalkTool number as a 3CX speed dial or BLF key for one-press access
- Your org code is the same for every agent on the account
- No 3CX admin or marketplace install is required to get started
2
On a live 3CX call, add a line to TalkTool
While you are connected to your customer, use the Conference control in your 3CX Web Client, desktop app, mobile app, or deskphone (or an attended/warm transfer) and dial your TalkTool conference number to bring it onto the call.
- In the 3CX apps this is the Conference action on the in-call screen
- On a deskphone, use the Conf soft key, then dial TalkTool
- If you prefer, dial TalkTool first and have it call the customer in step 4
3
Enter your org code, then the language
When TalkTool answers, key in your organization code and press #. Then enter the two-digit code for the language the other person speaks — for example, 01 for Spanish — so the interpreter knows which direction to translate.
- Enter digits using your 3CX dialpad / DTMF keypad during the call
- The two-digit code maps to the customer's language, not English
- A reference list of language codes lives in your TalkTool dashboard
4
Press 1 to dial out, or 2 if already connected
If you used 3CX to start a fresh call, press 1 and TalkTool will dial your customer and join everyone together. If the customer is already conferenced into the 3CX call, press 2 and TalkTool will begin interpreting the people already on the line.
- Press 2 for the most common case: customer already on the 3CX call
- Press 1 when you want TalkTool to place the outbound leg for you
- Merge the 3CX legs so all parties hear the interpreter
5
Talk normally and review the records
Speak naturally and pause briefly after each thought — the AI relays each side in the other language within a second or two. When the call ends, open your TalkTool dashboard to read the two-language transcript and the AI summary.
- Short, complete sentences interpret most cleanly
- Transcripts and summaries are saved automatically per call
- Billing is a flat $0.30/min for the interpreted time

Why add TalkTool to 3CX calls

Live AI translation on the calls you already make — nothing to install.

Works with your existing 3CX setup

Nothing to install in 3CX — no marketplace app, no API connector, no admin project. TalkTool joins as a conference participant over the phone network, so it works on every 3CX edition and endpoint.

60+ languages on demand

Pick the caller's language with a two-digit code at the start of the call. Switch languages call-to-call without any configuration in 3CX.

Live, ~1-2 second interpretation

The AI relays both sides of the conversation almost in real time, so your 3CX agent and the customer hold a natural back-and-forth instead of a stop-start exchange.

Flat $0.30 per minute

No app for your customer

The other party stays on the same 3CX call and simply hears a natural-sounding voice in their language. Nothing to download, sign up for, or configure on their end.

Transcript and summary every call

After you hang up, TalkTool saves a side-by-side two-language transcript and an AI summary to your dashboard for QA, follow-up, or your records.

Full guide

If your team runs 3CX, you can add live interpretation to a call without touching your dial plan, buying a marketplace app, or asking the caller to install anything. TalkTool joins the call as an AI interpreter over the phone, using the same Conference and warm-transfer controls your agents already use every day.

How TalkTool works on a 3CX call

3CX already gives every agent the controls needed to bring a third party onto a live call — the Conference action in the Web Client and desktop and mobile apps, the attended (warm) transfer flow, and the Conf soft key on supported deskphones. TalkTool plugs into that existing capability. Instead of conferencing another colleague, your agent dials the TalkTool conference number, and TalkTool answers like any other participant.

From there the flow is a short DTMF sequence on the 3CX dialpad: enter your org code and #, key in the two-digit language code for the caller (for example, 01 for Spanish), then press 1 to have TalkTool dial the customer or 2 if the customer is already on the line. The AI then interprets both directions live. Because none of this lives inside 3CX, there's nothing for your 3CX admin to provision — see how to conference in an AI interpreter for the full walkthrough.

AI interpreter vs. a human phone interpreter

Traditional over-the-phone interpretation means putting the caller on hold, dialing a vendor line, waiting in a routing queue, and briefing a human before anyone can talk — and then keeping a third person on every call. TalkTool connects in seconds, runs 24/7, and keeps the conversation to just your agent and the customer, with the AI relaying each side in about one to two seconds.

For routine business calls — appointment scheduling, order status, support tickets, billing questions — that's usually all you need. When a call legally requires a certified human interpreter, use one; for everything else, the AI is faster and dramatically cheaper. If you're moving off an incumbent vendor, the LanguageLine alternatives page covers the trade-offs.

Who at a 3CX shop benefits

3CX is popular with SMBs and mid-market teams running their own PBX — medical and dental offices, property management and HOAs, logistics and dispatch, municipal and utility front desks, home services, and outsourced contact centers. These are exactly the teams that field Spanish, Mandarin, Vietnamese, Haitian Creole, or Arabic calls without a bilingual agent free.

A receptionist on the 3CX Web Client, a dispatcher on a deskphone, or a queue agent on a softphone can all add TalkTool the same way, mid-call, the moment they realize there's a language gap. Because it's per-minute with no commitment, even teams that only hit a handful of these calls a week can keep it on standby.

What it costs

There's nothing to install and nothing to migrate, so the cost to try it is essentially one phone call. Full pricing is on the pricing page, and the reduce interpreter costs guide breaks down the savings against a typical OPI bill.

Live interpretation, no 3CX project required

Because TalkTool conferences in over the phone instead of integrating into 3CX, any agent can add a 60+ language AI interpreter to a live call in seconds, for a flat $0.30/min — using the Conference and warm-transfer controls 3CX already gives them.

3CX translation FAQ

Does TalkTool integrate with 3CX?

There is no native integration to set up, and you don't need one. TalkTool isn't a 3CX marketplace app or an API connector — it joins your call over the telephone network as a conference participant. Because it works at the call level rather than inside 3CX, it works with 3CX out of the box, alongside whatever extensions, trunks, and endpoints you already have. If 3CX can conference or warm-transfer in another number, it can add TalkTool.

How much does it cost?

Which languages are supported?

More than 60, including Spanish, Mandarin, Vietnamese, Tagalog, Arabic, Haitian Creole, Portuguese, Russian, French, Korean, and many more. You choose the caller's language per call by entering a two-digit code (for example, 01 for Spanish), so a single 3CX agent can handle a different language on every call.

Do my customers need an app?

No. The other party stays on the same 3CX phone call and simply hears a natural-sounding voice speaking their language. There's no app to download, no link to click, and no account to create. This works whether they're on a mobile, a landline, or any other phone.

Is an AI interpreter as good as a human interpreter?

For most everyday business conversations — scheduling, support, intake, billing questions, status updates — the AI is fast and accurate, and it removes the hold queue and the third human on the line. It connects instantly and is available 24/7. For settings that legally require a certified human interpreter, such as certain medical or legal proceedings, you should still use one. Many 3CX shops use TalkTool for the bulk of routine calls and reserve human interpreters for the few that require certification.

Which 3CX surfaces can I use this from?

Any of them. The flow is the same whether you're in the 3CX Web Client, the Windows or Mac desktop app, the iOS or Android app, a supported deskphone, or an agent's softphone. Wherever 3CX lets you conference or warm-transfer a number, dial your TalkTool conference number and follow the prompts.

Does this work for inbound calls on a 3CX queue?

Yes. When a call arrives through a 3CX ring group or call queue and the agent realizes the caller doesn't share a language, the agent conferences in TalkTool mid-call and presses 2, since the caller is already on the line. Interpretation begins within seconds without dropping or re-routing the call.

Will my 3CX call recording and reporting still work?

Yes. The interpreted call is a normal 3CX call, so your existing 3CX recording, CDRs, and reporting behave as they always do. On top of that, TalkTool separately stores a two-language transcript and an AI summary in your TalkTool dashboard for each interpreted call.

Your next conversation can speak their language.

Add a live AI interpreter to your next 3CX call for a flat $0.30/minute — conference it in or let it dial your customer. No contract, no app for the other side.
