EDIT: RESOLVED! I deleted/reinstalled google voice on the new phone one more time.
I've been using Google Voice for a full year now so that I have a second phone number on my cell phone that I can give to clients instead of my personal number, and an easy way to sort work texts and personal texts, etc. I haven't had any trouble and it has worked great! Up until now.
I upgraded to an iPhone XS over the weekend, and although I can see that I received calls, send and receive texts, and access all of my google voice contacts just fine, I can't make outgoing calls. Both phones are running the same operating system, and the iPhone XS was udpated using a restore from my old phone
