I use Zendesk talk on a daily basis from past 4 years. ZD talk is being used by the company which I am working for and all our other sister concerns as well. ZD Talk has been separated by Brands in the system and we are managing the companies. Calls come in and go out from the Software and it is very rare that we face an issue and mostly it is fixed with a little bit of tweaking in the settings or providing privileges. Our whole software support team and professional services use the product to interact through it and get all personnel updated. I have myself asked many of the IT industry users to opt ZD Talk as it can be used flawlessly with less internet speed as well and it does take much of the internet usage. Overall, I have been very satisfied with the product.
