@Russ Yes I actually believe I am one of the first novice people to use home automation Ringcentral smartthings Yealink phone alexa and trigger cmd to automate my home. I put all those things together so if someone googles Yealink and home automation they will find this post and know it is possible (and supper easy)
For me (since I use my computer and Triggercmd to control my monoprice zone amp) I only needed my Yealink VOIP Phone (that includes an Action URL page in the admin software) and your Trigger CMD Bookmark option .
I also used your (AI Tool .bat generator) that (Trigger CMD) fires off (on my computer to mute my stereo) when it receives a http request(with the link made from your Bookmark button) from my Yealink phone.
So when I get a phone call (or pick up the handset to make a call) on my Yealink T57W, it automatically mutes my stereo and then un-mutes when I end the call.
I can even have it turn my lights green so my kids know I am on a call (when they walk in after school (so they will be quiet and I can seem more professional)
Anyway I did not see any other ideas out there for my particular situation (and equipment) that did not involve custom code... and then I remembered Trigger CMD and eureka!!!
Just amazing what you have built here and it is good to be back
