Gavalox Communications was a subspace comm center on Rix Road on the planet Ferrix, that offered public comlink stations where people could insert credits to use comlink booths. The comm center offered "multi-network access" and "pay as you go" services that were available 24/7. The sign on comm center stated the business' name in Aurebesh at the top and Bazeese script at the bottom. The business name was also written in Bazeese on a street lamp, two lines of the same words wrapping around it, but with different color hues.
The comm center was located close to Ferrix Depot, Hotel Rix and a store selling chairs.
In 5 BBY, Timm Karlo went there to make an anonymous tip call about Cassian Andor, who was wanted by the Pre-Mor Security Inspection team for questioning. Each booth contained a large comlink with various buttons and green monitor saying "INSERT CREDIT" in Aurebesh, with the credit symbol underneath. After Karlo pressed a series of buttons, the message "COM LINK DT" appeared.
Gavalox Communications was created for the television series Andor. Barry Gingell, who worked as a graphic designer on the series, confirmed on Twitter that the script that runs underneath the Aurebesh name on the sign was a new alphabet created for the series, but he was not in a position to reveals its name. The name of the script was eventually revealed to be Bazeese script, in the episode guide for the episode "Rix Road."
