Sure. So if you say can I call you about X/Y/Z, you're asking them to stop what they are doing and listen to your monologue in real time. With the walkie talkie, you hit talk and send them your monologue. They can listen in real time (one-way) if they are available or can listen to your audio + read the transcription (later). This puts them in control of when and how they consume and respond. The added benefit is they can relisten or re-read before responding. I find it puts me in control of context switching
