Warm vs Direct (Cold) Transfer: Choosing the Right Mode

Warm vs Direct (Cold) Transfer: Choosing the Right Mode

When your AI receptionist transfers a call to a human, there are two ways it can happen: warm transfer and direct transfer.

In the SkipCalls app, Direct transfer is the same as Cold transfer. Turn Direct transfer on to connect the caller immediately. Leave it off to use a warm transfer, where your receptionist briefs you before connecting the call.

What's the Difference?

Warm Transfer

Direct Transfer (Cold Transfer)

How it works

AI calls you first, briefs you about the caller, then connects them after you accept

Caller is immediately forwarded to your phone — no briefing, no approval step

Speed

Takes longer (15–30 seconds for the briefing + accept flow)

Instant — caller hears ringing within seconds

Context

You know who's calling and why before you pick up

You pick up blind — no context about the caller

Caller experience

Hears hold music while AI briefs you

Hears standard ringing, feels like a normal call forward

You can decline?

Yes — AI continues the conversation if you decline

No — call goes through immediately, like regular forwarding

Warm Transfer (Default)

This is the default mode and works best for most businesses. Here's what happens step by step:

  1. AI tells the caller: "One moment, I'm connecting you now"

  2. Caller hears hold music

  3. AI calls your transfer number in a separate conversation

  4. AI briefs you: who's calling, what they need, and a quick summary of the conversation so far

  5. You accept or decline the transfer

  6. If accepted, the caller is connected to you directly and AI steps out

Best for: High-value calls, sales inquiries, complex support issues — situations where knowing context before picking up helps you serve the caller better.

Direct Transfer (Cold Transfer)

Direct transfer — traditionally called cold transfer — skips the briefing entirely. The caller is forwarded straight to your phone, similar to traditional call forwarding:

  1. AI tells the caller: "One moment, I'm connecting you now"

  2. Caller is immediately forwarded — they hear ringing

  3. You pick up as you would any normal call

Best for: Simple call routing, receptionists, situations where speed matters more than context, or when you already know who's likely calling (e.g., a dedicated support line).

What If You Don't Pick Up or It Hits Voicemail?

This is an important difference between the two modes:

Warm transfer: The AI calls your number to brief you. If you don't answer or the call hits voicemail, the AI cannot complete the handoff. The transfer fails and the AI returns to the caller with an error — the caller gets a poor experience.

Cold transfer: The caller is forwarded directly to your phone. If you don't pick up, the caller reaches your voicemail and can leave a message — just like a normal call. No dead end.

Recommendation: If there's a chance you won't always be available to answer, use cold transfer. That way the caller can at least leave a voicemail instead of getting bounced back to the AI with an error.

How to Manage Transfer Numbers

You can add multiple transfer destinations for the same receptionist. Each number has its own name, instructions, transfer mode, availability, and active switch.

  1. Open Settings → Receptionist Settings → Call Transfer

  2. Tap Add Number, or tap an existing number to edit it

  3. Enter the phone number and tap Continue

  4. Add a short name, such as sales or support, and describe when your receptionist should use this destination

  5. Turn Direct Transfer on for an immediate cold transfer with no briefing, or leave it off for a warm transfer

  6. Optionally turn on Limit Transfer Hours, then tap Add Number or Save Changes

On the Call Transfer page, use the switch beside a number to make that destination active or inactive without deleting it.

Each transfer number has its own mode. For example, you might use warm transfer for your sales line so you hear the lead context first, and Direct (Cold) transfer for your front desk where quick pickup matters most.

What Happens If Warm Transfer Fails?

If the warm transfer cannot be completed (e.g., the briefing call fails for technical reasons), the system automatically falls back to a cold transfer. The caller will still be connected — they just won't get the briefing step.

Frequently Asked Questions

Can I use different modes for different numbers?

Yes. Each transfer number has its own transfer mode. You can set sales to warm and support to cold, or any combination you need.

Which mode should I use if I'm not sure?

Start with warm transfer (the default). It gives you more control and context. Switch to cold if you find the briefing step adds unnecessary delay for a specific number.

Does the transfer mode affect billing?

Warm transfers use slightly more minutes because the AI makes a separate call to brief you. Cold transfers are quicker and use less time.

Will the caller notice the difference?

Yes. With warm transfer, they hear hold music for 15–30 seconds. With cold transfer, they hear ringing almost immediately. Both start with AI announcing the transfer.
