If a client prefers to communicate online, invite them to a Telegram chat. The chat history is saved in the CRM entity timeline.

To use this feature, connect your Telegram bot to Bitrix24.
How to connect Telegram

The client will receive an SMS with an invitation link. After they open the link and start the chat, you can access the conversation from the deal timeline.
