Signalstream logo concepts
Four marks for Signalstream, each shown with the wordmark on light and dark grounds, as an app icon and at favicon sizes. All four use the same two colors as the site: switchboard ink and live-line teal. Source SVGs are in assets/logos/. Back to the site.
Beacon pulse
A source point sending out two rings of signal. It nods to the Beakon name, reads as "broadcast" and "on call", and stays legible at 16 px because it is three shapes.

Signal path
An S drawn as one routed line between two endpoints: the call comes in at one node and the message leaves at the other. The most literal "stream", and the strongest letterform.

Line lamps
Five bars, one for each line in the operator's rail, with the live line lit. It doubles as an audio waveform, which suits a telephone product, and animates well as a loading state.

Message pulse Used on the site
A message bubble carrying a heartbeat trace. It says "messages" and "medical" at once, which fits the HIPAA story, but leans harder on healthcare than the other three.

Recommendation
Message pulse is the chosen direction and is now used on the site and as the favicon. The message is the product's core object, and the trace keeps it from reading as a generic chat icon. At 16 px the trace gets tight, so a final favicon may want a slightly heavier stroke. Beacon pulse and Signal path remain as alternates.
