Someone please explain to me why a phone call is different to this, I'm truly blanking.

I dig this. This is what I am thinking.

Much easier to click than dial.

Social cost of a web link versus a phone number may be lower as well (that may be cultural but it may be true)

Adds other modes like calendar or chat or AI directly in flow.

No need to reveal a phone number.

Internationally accessible (no long distance)

And for HN tradition’s sake for these types of comments, no one likes rsync.

Congrats on launching!

Curious how the dynamic image works in the e-mail signature: AFAIK, Gmail and others heavily cache any images inside e-mail, so even if the image changes, Gmail will be displaying the online/offline cached image, not the most up-to-date one.

You can overcome this using headers, which instructs Gmail not to cache. Snippet:

response.headers["Cache-Control"] = "no-cache, no-store, max-age=0, must-revalidate"

response.headers["Pragma"] = "no-cache"

response.headers["Expires"] = "Fri, 01 Jan 1990 00:00:00 GMT"

A few:

- assign calls to different members (round-robin, escalation)

- capture lead info (name, email, etc)

- don't reveal actual phone number

- recording, transcription

- soon, conversational AI agent (as optional backup)

With a WhatsApp/phone, you can't really switch it from one employee to another easily. Managing load is harder, seeing call logs is harder. And a full call center solution is too much for a small business.

This might be a silly question: I understand that to talk, the caller uses their web browser with device audio. What does the link creator use?

If the creator has the app (onair.io/ios , onair.io/android), they would receive notifications there and can take the call. Also, if a browser is open when someone calls them, they would also receive notifications there as well.
