Twilio.Got it. You may just have me stumped on my first test.
The reason I was asking if you were leveraging a comms partner (Twilio, Bandwidth, Vonage, etc) is because their carrier relationships may be what bypasses whatever upsell or restricted access exists. Though, I don't know.
I sent a note to our carrier relations team to see what they may have on this.
However, Twilio is not the issue. I say this because as soon as a CNAM is changed in Twilio, it immediately shows with most Mobile Carriers. I tested one about 3 minutes after the Twilio Update, and it was updated with US Cellular.
My goal certainly wasn't to stump you or in any way embarrass you. You were clear that this really isn't your area of expertise. I understand that for sure.
