Speakerbus, a supplier of advanced voice solutions for the financial and command and control markets, recently completed interoperability testing of CTI group’s Proteus Trader call accounting application with Speakerbus’ iTurret dealer board. The iTurret utilises IP-PBX infrastructure on either Avaya or Cisco to deliver a significant return on investment, compared to traditional trading platforms.  By reducing the back room footprint clients are able to reduced cost, minimize complexity and optimise support skills. Clients also gain access to seamless line sharing and direct access to PBX features. John Graves, Product Manager at Speakerbus, stated, “The successful compliance testing of CTI Group’s Proteus Trader with Speakerbus’ iTurret provides customers with the assurance of robust product interoperability, which further strengthens our iTurret value add, to both new and existing customers.” John continued, “By providing interoperability with Proteus’ specific trader focused features, especially the private wire inventory and trader reporting functions, our customers will be able to choose an application that greatly enhances their trading platform. As a well respected vendor within the financial services industry, we are always keen to expand our ecosystem of partner applications. By providing customers with a choice of applications that enhances our iTurret value proposition we are exceeding the needs of our multinational clients.” Customers will be able to take full advantage of this certification in Speakerbus’ upcoming Q2 release of iTurret (V1.3). © 2026 - Speakerbus ### NEWSLETTER ## Want to stay up to date ?
