For info on the Cisco approach, refer to
Accessibility testing Our solution relies on various vendors components such as Cisco. The UC solution may use Cisco technology where Cisco has adopted accessibility development, testing and overall conformance for their Web-based products. Cisco has directly stated that the following:

“The Accessibility Initiative identifies global accessibility and usability requirements and establishes strategies and processes to integrate accessibility throughout Cisco operations. Cisco's commitment is to make its products, services, websites, and documentation accessible and usable by people with disabilities, either by design or through compatible use with assistive technology.
The following key objectives for company business processes and activities help ensure that Cisco products and services benefit the disabled community:

Increase awareness of accessibility within Cisco provide employees with the training needed to design, produce, market, and deliver accessible products, websites, and documentation

Develop and apply policies and guidelines to evaluate accessibility, usability, and compatibility with applicable equipment, services, websites and documentation

Evaluate accessibility and usability throughout the product design, development, and fabrication processes as early and consistently as possible

Report ways these guidelines are implemented where competitively, technically, and economically feasible
Involve people with disabilities in research projects, testing, and trials

Support and contribute to industry standards and guidelines for accessibility”
