I deliver VoIP services to my customers and i use 90% of the time the Yealink SIP phones. The problem in 50% of the cases is that when the client is turning on their voicemail, they can't see it anyway if it is turned on yes or no.
I know it is possible to use something with XML and a webserver to create a connection with the phone which can enable / turn on a led to indicate a button is pressed with a specific command, like enable voicemail.
When the client presses an other button, it should disable the led and execute a specific command.
I need you to get this done, i can do all the testing, but i have no clue where to start.
I know a competitor has made something like this and it where a few files on a webserver which he was calling from an action programmed on a button of the phone, so it can't be that difficult.

Hello! I'm VoIP expert with mlre than 7 years experience! I had projects with Yealink phones as well: I can help you configure LED on key press. But need to discuss details with you!
We can control the phone behavior directly using Action URL and force the phone to behave depending on user inputs on the keypad. For more details please contact me to discuss your requirements directly.
