As someone who does a Vidcast & has phone guests. Having the guests phone number show is not good.
Hiding the caller ID. Like having it simply say phone participant to others in the call & when recording & live streaming by default.
Even better would having the option where the host can rename the phone contact and change add a photo or gif have been remembered for returning callers as well.
I can crop or blur it out in editing. Also try to allow people I trust to see the participants phone number but this is a an important feature to add especially if anyone ever plans to do a live episodes with phone guests.
Keep on rocking and improving this amazing service.
