Broadcast Radio multi-line call-in systems for studio phones

Description

Broadcast Radio sells and supports multi-line call-in systems for radio studios, including AEQ Systel systems. The page explains how Systel 16 and SystelSet+ can provide multiple SIP lines, call queues, and routing to air. The product information is mainly about studio telephony hardware and control rather than contest software. It includes options for multiple lines in a single studio, multiple studios, call queue management, and routing callers directly from the control interface. This can support call-in contests by providing studio call capacity and queue control. The fit is less direct than a dedicated prize or promotion-management system, so the entry should be reviewed before adding to the contest systems category.
