ADDASOUND Crystal 2871/2872 headset solutions help businesses deliver a better customer experience, increase productivity and reduce operational costs. ADDASOUND Crystal 2871/2872 QD headsets using the ADDASOUND DN1002 direct connect cable are now compliance-tested by Avaya for compatibility with the Avaya 9600 Series IP Deskphone H.323 Release 3.2.6 and SIP Release 2.6.16. ADDASOUND Crystal 2871/2872 headsets using the ADDASOUND DN1002 and DN1008 direct connect cables are now compliance-tested by Avaya for compatibility with the Avaya 1600 Series IP Deskphone Release 1.3.9.

ADDASOUND is a Technology Partner in the Avaya DevConnect program—an initiative to develop, market and sell innovative third-party products that interoperate with Avaya technology and extend the value of a company's investment in its network.  

As a Technology Partner, ADDASOUND is eligible to submit many headset types for compliance testing by the Avaya Solution Interoperability and Test Lab. There, a team of Avaya engineers develops a comprehensive test plan for each application to verify whether it is Avaya compatible. Doing so enables businesses to confidently add best-in-class capabilities to their network without having to replace their existing infrastructure—speeding deployment of new applications and reducing both network complexity and implementation costs.  


"Compliance with these Avaya IP Deskphones means businesses can confidently deploy ADDASOUND's Crystal 2871/2872 wired headset solutions in contact centers and offices with an Avaya communications infrastructure. ADDASOUND headsets seamlessly integrate with Avaya communications platforms so customers can enjoy clear voice transmission while minimizing operational costs and increasing work efficiency.”

By successfully completing Avaya compliance testing, ADDASOUND headsets have demonstrated proven interoperability and seamless integration with the Avaya platforms used in contact centers and enterprises."
