I searched the site and didn't see these anywhere... so I'll post here.

This chat software will be used by customer support:

When a Chat ends, can it or does it ask for customer feedback?

When a Chat is requested, can it or does it send a text message to the person on duty, who can click a link in the text message and chat with customer on their mobile device?

Thanks in advance.

Both of your features will require customization .
