Enterprise users with hearing loss can now listen and read captions directly on their Cisco® desk phone.

Introducing Hamilton® CapTel® for Business Interconnected by Tenacity

We have partnered with a top tier captioned telephone provider: Hamilton® CapTel®. Thanks to this partnership and our long relationship with Cisco, we have created a service that provides captions directly on the Cisco phone. Businesses can seamlessly integrate captions into their Cisco VoIP network, providing employees with hearing loss the efficiency and effectiveness of using their existing office telephone.
