Do the IP restrictions set in Zendesk Support also apply to Zendesk Chat?
The IP restrictions apply to Phase 3 and Phase 4 Chat accounts and do not apply to Legacy Chat accounts. For more information on how to determine your chat version, see the article: Determining your Zendesk Chat account version.
Unique behavior for Phase 3 Chat accounts
If a Chat agent is already signed in to the Chat dashboard before setting up the IP restriction, it does not force the chat dashboard session to end. The restriction happens when they reload or sign back in.
