Third party blocking service seems to intercept calls from this number.

We got a call from this number with CID name set to "BALTIMORE SUN" today.  It rang only once and did not call back.  Our third party blocking service (rhymes with SlowNoHobo) intercepts calls after the first ring if the caller ID number is on their blacklist or triggers their "Advanced Robocall Detection" algorithm(s,) so it's likely they're already clamping down on calls from this number.

I check 800notes when the blocking service nixes a call in case there's a mistake.  I'm posting about my recent call in case knowing this CID number is already on the service's radar helps anyone else.
