Review on Calisto P820 Mobile Discontinued Manufacturer by John Sprunk

According to my experience, this portable conference phone is an excellent choice for on-the-go meetings. The sound quality is crystal clear and the design is sleek and modern. The convenient carrying case makes it easy to transport and set up. The only drawback is that it may not be able to pick up voices from very far away, but this can be solved by positioning it closer to the speakers. Overall, a great investment for any professional in need of a high-quality conference phone.
