I would like to create conditions based on trigger phrases. For example, one of my topic is about phone system. The trigger phrases are:
I'd like to check if the trigger phrase contains "voicemail", redirect them to a Voicemail topic and if it's other, redirect them to a different topic.
Is that possible?
Best practice is to define the trigger according to your topic. So if you want a topic triggered by the word "voicemail" then use that in your trigger phrase.
If you want to get the text that triggered your topic you can access it via the variable Activity.Text : you can use that variable in a formula to extract/filter/identify specific keywords and create a condition on it (like does the text contains the word "voicemail"?)
