We're an MSP, rolling out our first 3CX system, and we're looking for some functionality that we haven't been able to find. I think it might be handled by EVENTLIST BLF, but I can't seem to find any documentation. What we're looking for is for a BLF 'speed dial' to indicate the state of an extension: Available On the phone Set to DND/Not available Simply setting the programmable button to BLF shows whether the target extension is actually in use or not, but does not indicate any additional status information. We have situations where there may be a meeting going on in someone's office, and it'd be helpful for the receptionist to be able to tell with a glance: "I'm sorry, Dan is in a meeting right now." If the user at the target extension either (a) sets status to an unavailable status, or (b) sets DND=On, there's no change to the BLF light on the receptionist's set, but phone calls to that extension are automatically sent to voicemail. Does anyone know of any way to handle this? I thought it might be handled by EVENTLIST BLF, but I can't find any documentation on the server side at all. I found the documentation on the XML tags used in the file, but can't find any documentation on where to save the file on the 3CX server. Has anybody tried this before, or found another way to implement the same functionality?
