About CallAgent

CallAgent is three things in one: a platform for building voice agents, a SIP PBX and a contact centre. Not because they sounded good together, but because anyone who puts a voice agent on a real number needs an IVR, a queue and somebody to escalate to within a fortnight.

The agent side is provider-agnostic. You pick the transcriber, the model and the voice per assistant, and the latency and cost sit on the card you pick them from.

The interface is dark first, dense, and uses colour only for status. The three rules are written at the top of the theme file and have not changed since.

This site continues them. The same colours, the same monospace for anything numeric, the same seven hues for the seven stages of a call. If the page looks like the product, that is on purpose.

The second rule is the less usual one: no figure on screen may look measured if it is estimated. A cost derived from list prices is prefixed and says what it is. A latency we did not measure says so. The rule starts in the product and applies here too.

There is a status page saying what has been proven and what has not, a changelog kept from the real work, and a “what does not work yet” section at the end of every guide.

That is not humility. It is cheaper: a customer who finds out in month three that a feature does not exist leaves, and one who read about it first stays.
