How are you handling external VoIP incoming calls to see GHL contact info?

I’m trying to figure out the most efficient way to get caller context when using a third-party VoIP alongside GHL.

Right now, the biggest friction point is that when a call comes in, I'm flying blind. I don't know the caller's pipeline stage or recent notes until I manually search their name in GHL after answering.

Has anyone successfully built a reliable integration (maybe via webhooks to Zapier/Make) that pushes an instant Slack or desktop alert with the GHL contact info while the phone is still ringing?

I'm mapping out a custom API build for this, but I'm curious to hear what setups are actually working for you guys in production without being too laggy.
