Lync Phone Edition has no attendant console and does not integrated to the Lync Attenant Console. snom has their snom Vision and Polycom VVX is planning to introduce an expansion module.
Audiocodes notes that their 400 series will support an “optional tablet expansion for attendant console”. The brochure (below) and press release do not note if the “tablet” is a standard Windows or Android tablet, or if it is some proprietary “module”.
