A new translation was suggested because the current one says that the call is “agora” (“now”), but the English version says it is “within next few seconds” (“em segundos”).

Not every word or sentence should be translated at a direct translation. Each language has its own way of interpretation, which varies from context, locations, culture and time, for example. In this case, "breve" has been omitted, because it is not relevant for the context. Thus, "Dentro" has been used as a pretty much way of saying it in informal dialogues. It worths mentioning that the comma is used to separate the first dependent clause from the second independent clause.
