Hi there,
I went through all 3 of your linked videos but I am a bit stumped as to what the takeaway should be from all of them.
The integration process shown is very similar to our own and so are the features mentioned with the exception of the form functionality presented.
I am not trying to be smart or rude here but if you would like a chat like Zoho Desk then why not simply use that one? Like all things variety is the spice of "Live Chats", some are built around certain needs & requirements and others are built around their respective platform purpose. (i.e. 3CX)
Are there any specific suggestions you would like to make in regard to the 3CX live chat?
