Warm transfer

What it is

In telephony, a warm (attended) transfer means the transferring party speaks to the recipient before connecting the caller. For a voice agent, "warm" also means the context travels: the recipient's screen shows the transcript or a summary, the caller's identity and the data already collected, so the first human words are not "how can I help you today?".

A cold transfer sends the caller to a number or queue and hangs up. Everything the agent learned is lost, and the caller repeats it. Many products advertise warm transfer but deliver a cold transfer plus an email of the transcript that arrives after the call.

Why it matters when buying

Transfers are where agent and human meet, and the caller's memory of the call is often formed there. Whether a warm transfer is possible depends on your telephony and contact-centre platform: can the agent hold the caller, dial the recipient, wait for an answer, whisper a summary, and bridge? Does your platform expose a screen-pop or a data field the agent can write into? These are integration questions that take weeks, not a checkbox.

What to ask

Ask to see a transfer end-to-end in the demo: what the caller hears, what the recipient sees, and what happens if nobody answers. Ask whether the agent can announce the caller to the recipient before bridging. Ask how transfers work outside staffed hours (callback, voicemail, message). Ask which contact-centre platforms are integrated for screen-pop rather than email.
