I've just gone through setting up the WhatsApp integration, and I think there are some steps missing from the guide that will help people get the integration up and running more quickly & smoothly:
- Switch the App in WhatsApp Manager to be "Live"
- In 3CX ensure the destination of the WhatsApp Trunk is an Extension or Ring Group (or possibly a Call Queue - I've not tried that) that has the users you want in it - the default for me was the DEFAULT group and this did not work
- I'd say the guide should just point people to the Management Console as well, as it wasn't possible to change the destination in the Web Client (or if it is it is not obvious)
- When making changes to the destination make sure that the chat is fully resolved (Take, Dealt With) as the chat seems to "stick" with the previous destination settings
- This drove me up the wall thinking I was going nuts with test messages coming from my WhatsApp number going to completely the wrong place ...until we "dealt with" the existing chat
