Can you tell us how the HubSpot Integration is expected to work? Hubspot should have something, somewhere, that tells you how to connect to “Asterisk”. Generally, there’s something in he documentation that calls out the “web interface” so that the pop-up feature can work. Once you know what Hubspot needs, we can help you craft an interface string, which (hopefully) you will then send to Sangoma and say “Add this to your list of recipes.” This way everyone wins.
By the way, there are several people on here that love to do this kind of “one off” stuff, so I’ve no doubt that someone will be able to get you going.
