How to transfer a call

Warm transfer (also called attended or consultative) means you put the caller on hold, reach the other person first, explain who's calling and why, and then connect them. The caller arrives expected.

Blind transfer (also called cold or unattended) means you send the caller straight to the destination without speaking to anyone first. It's faster, but if nobody picks up, the caller lands in an unfamiliar voicemail — and on most systems the call is gone from your side, so you can't recover it.

Rule of thumb: blind transfer is fine for a switchboard routing a caller to a department they explicitly asked for. Use a warm transfer for anything where the caller has already explained their problem, so they don't have to explain it twice.

The exact labels vary by manufacturer, but nearly every desk phone follows the same sequence.

Warm transfer:

1. Press Transfer (sometimes labelled Trnsfer, TRAN, or shown as an icon). The caller goes on hold.
2. Dial the extension you're transferring to.
3. Wait for them to answer, then tell them who's on the line and what it's about.
4. Press Transfer again — or hang up — to connect the two and drop yourself out.

Blind transfer:

1. Press Transfer, then Blind if your phone offers it.
2. Dial the extension.
3. Press Transfer again or hang up immediately, without waiting for an answer.

If the destination doesn't pick up during a warm transfer, press the line key for the held call (or the Cancel / End Call softkey) to return to the caller before they're stranded.

Softphone apps — RingCentral, Dialpad, GoTo, Zoom Phone, Teams and the rest — put transfer in the call window rather than on a keypad:

1. Click Transfer during the call.
2. Choose Warm / Ask first or Blind / Transfer now.
3. Pick the person from the directory, or type an extension or full number.
4. Confirm to complete.

Most of these systems can also transfer a caller directly to someone's voicemail without ringing their phone — useful when you know they're out. It's usually a Transfer to voicemail option in the same menu.

Some systems also expose a dial-code shortcut for blind transfer, but the code differs between providers, so check your own documentation rather than assuming a standard one.

A regular mobile call cannot be transferred. There's no transfer function on the cellular network for a consumer line, and no button for it in the iOS or Android dialer. What works instead:

Merge and drop out. Tap Add Call, dial the third person, then tap Merge Calls to join everyone. Once they're talking, tap End to leave — on most carriers the other two stay connected. This is the closest thing to a warm transfer on a mobile, and it's the method most people mean. Step-by-step on how to make a conference call on iPhone and how to do a 3-way call on Android.

Forward the line in advance. If you know calls should reach someone else, set conditional forwarding before the calls arrive rather than trying to move them mid-call. See how to forward calls.

One caveat on merging: whether the remaining two stay connected after you hang up depends on the carrier, and it isn't guaranteed. Tell both parties what you're doing before you drop off.

A transfer goes wrong in the handover, not the button press. A workable script:

To the caller, before you transfer: "I'm going to put you through to Dana, who handles scheduling. One moment — and if we get cut off, her direct line is 555-0123."

Giving the direct number before you transfer is the single highest-value habit here. If the transfer drops, the caller can get back in without starting over.

To your colleague, during a warm transfer: who's calling, what they need, and anything they've already told you. Fifteen seconds of context saves the caller repeating themselves.

If nobody picks up: go back to the caller rather than dumping them into voicemail. Offer to take a message or arrange a callback — a caller returned to a real person tolerates a failed transfer; one that lands in an unexpected voicemail often just hangs up.
