Warm Transfer Acceptance for Voice AI Assistants

Telnyx has launched Warm Transfer Acceptance for its Voice AI Assistants, enabling transfer recipients to verbally accept or decline calls before the caller is bridged. The feature, available via API configuration, adds a live consult step to screen calls and prevent dropped transfers, with the `complete_transfer` tool added automatically when enabled.
