Warm Transfer Acceptance is now available for Telnyx Voice AI Assistants. Recipients of a transfer can talk to the assistant and verbally accept or decline the call before the caller is bridged, giving teams control over which calls get through.

`private`

mode, or preserve it in the record with `shared`

mode.`complete_transfer`

tool is added to the assistant automatically when acceptance is enabled. No extra configuration needed.A standard warm transfer plays a recorded handoff message and bridges the call whether the destination is ready or not. That means dropped calls, transfers to unavailable agents, and frustrated callers left in dead air after a handoff. Warm Transfer Acceptance adds a live consult step so the destination can screen the call, hear the context, and decide whether to take it. The caller stays with the assistant hearing ringback and never hears the exchange. This is call control that normally requires a separate contact center vendor, built into the same platform that runs the assistant.

`warm_transfer_instructions`

to your handoff message.`warm_transfer_acceptance`

on the transfer tool by setting `enabled`

to true.`end_user_target_context_mode`

to `shared`

to keep the consult in the conversation record.
