Business chat is different from regular instant messaging. It should absolutely secure and make it easy to find a co-worker of interest. It should take company structure and permissions into account. Bitrix24 does just that.
Business chat is just one of many RTC tools that Bitrix24 has to offer.
Unified Communication means that all the tools that you are using to communicate with fellow employees, clients and business partners are available to you in one place. That’s Bitrix24.
