# Telephony

> Make and receive phone calls through Jam Assistant.

Jam Assistant has a phone number. Call it from any mobile or desk phone and have a full voice conversation with CRM access - no app, no browser, no internet connection required on your phone.

Telephony is the right channel when you're completely hands-free: driving between customer visits, calling from a hotel room desk phone, or when your mobile data is unreliable.

## How It Works

Jam Assistant recognises you by your caller ID. When you call from a registered number, Jam Assistant loads your CRM connections, Playbook rules, and Memory entries - and you're immediately in a full-capability session, just like a browser voice call.

### Registered Caller (full access)

1. Dial Jam Assistant's number from your registered mobile
2. Jam Assistant matches your caller ID to your account
3. Your CRM, Playbook, and Memory load automatically
4. Speak naturally - Jam Assistant can search, update, and create CRM records

### Anonymous Caller (demo mode)

If you call from a number that isn't linked to a Jam Assistant account:

1. Jam Assistant detects your phone prefix and selects a language automatically (e.g. `+49` → German, `+33` → French, `+34` → Spanish, English by default)
2. Jam Assistant introduces itself and offers a demo experience
3. CRM tools are not available - no data is read or written
4. You'll be guided to register your number for full access

## Finding Jam Assistant's Phone Number

Navigate to **Customize > Integrations** in the web app. At the top of the page, in the **Jam Assistant is everywhere you are** section, you'll find:

* A **tap-to-call** link with Jam Assistant's phone number
* A **QR code** to save Jam Assistant as a contact on your phone (scan once, call anytime)
* A **WhatsApp** button to open a chat session

Save Jam Assistant's number to your phone contacts so it's always one tap away.

## Registering Your Number

To get full CRM access on phone calls, your mobile number must be registered in Jam Assistant.

1. Navigate to **Customize > Integrations**
2. Enter your number in the **Add your number to reach Jam Assistant via Phone** field
3. Use international format - e.g. `+49 170 1234567` or `+1 415 555 0100`
4. Click **Save**

From that point on, every call from that number gives you full access.

## When to Use Telephony vs Other Channels

![Channel comparison - when to use phone, browser voice, WhatsApp, or web chat](https://29wltymfijnuhx9o.public.blob.vercel-storage.com/docs/product/images/telephony/02-channel-comparison.png)

| Channel           | Best for                             | Requires                     |
| ----------------- | ------------------------------------ | ---------------------------- |
| **Phone call**    | Hands-free, no internet, any phone   | Registered number            |
| **Browser voice** | At desk, want to see action cards    | Desktop browser + microphone |
| **WhatsApp**      | Quick updates from mobile            | Registered number + WhatsApp |
| **Web chat**      | Detailed work, reviewing CRM changes | Browser                      |

**Choose Phone Call when:**

* You're driving and can't touch your phone
* You're in an area with no mobile data (calls use cellular voice, not data)
* You're calling from a desk phone, hotel phone, or shared device
* You want a completely audio-only, distraction-free experience

**Choose Browser Voice when:**

* You're at your desk and want to see action cards confirming CRM changes
* You want a call summary automatically generated after the session

## During a Call

A telephony call works exactly like a browser voice call:

* Speak naturally - Jam Assistant listens and responds in real time
* Jam Assistant performs CRM actions while you talk (search, update, create)
* You can interrupt Jam Assistant mid-sentence
* Say *"goodbye"* or hang up to end the session

Unlike browser voice, there are no visual action cards during a phone call. After the call, the session and any CRM actions appear in your [Chat History](/external/assistant/chat-history).

## Tips

* **Save Jam Assistant's number as a contact** - scan the QR code on the Integrations page once and you'll have it permanently.
* **Debrief while driving** - *"Jam Assistant, I just left Acme Corp. Move the deal to negotiation and log a note that they're asking for a 10% discount."* Done before you reach the motorway.
* **Prepare for a meeting** - *"What's the latest on TechStart? Who are the key contacts and what's the deal stage?"*
* **Use your Playbook slash commands** - say *"slash debrief"* or *"slash prep TechStart"* to trigger your personal commands by voice.

## Troubleshooting

**Jam Assistant doesn't recognise me / gives a demo experience**
Your number isn't registered. Navigate to **Customize > Integrations** on the web, enter your mobile number in the **Phone** field, and save. Then call again.

**Call dropped or no response**
Telephony uses standard cellular voice. If the call drops, redial. Jam Assistant will resume with context from earlier in the same session if you call back within a few minutes.

**Jam Assistant responded in the wrong language**
Jam Assistant auto-detects language from your phone prefix for anonymous callers. For registered callers, language follows your Playbook settings. To change it, update your personal instructions in **Customize > Playbook > My Settings**.

**CRM actions aren't showing in Chat History**
Phone sessions appear in the **Actions** page after the call ends - refresh the list if the session isn't visible yet.
