This isn't a Ringcentral question per se but I wanted to know if there's any tools that integrate with Ringcentral that could do this.

Here's a video from Google Adwords of what I'm trying to accomplish https://youtu.be/1HY-8HBQMk0?t=107 (linked to the relevant time).

This video is from this article https://support.google.com/google-ads/answer/6100664 (a more specific article can be found here https://support.google.com/google-ads/answer/6095883)

So this seems to use a javascript code that changes the phone number on your website so we can track calls that originate from Adwords.

Is there a third-party tool and allow me to use this with other sources? Like if our yelp page links to our website using a URL like www.website.com/telephonesource&=yelp it would then display a call tracking number specific to Yelp?

We already have the call source numbers. I just don't have the tool that would modify the website to show the right number based on the source.
