Comcast Block Calls May 2026

Clara didn’t press 1. She’d read the news. Instead, she called her neighbor, Leo, a retired network engineer who still kept a vintage UNIX terminal in his garage for fun.

Denise frowned. “Ma’am, if you’re having call issues, we can swap your modem—”

Comcast never apologized. But the next week, Clara noticed a new option in her account settings: Call Forwarding Verification Alert. She enabled it.

It rang once on her end, then went silent.

They had been seconds away from draining her savings.

Leo smiled grimly. “We stop trusting the network to protect us. We use encrypted messaging for real conversations. We call back on a different line to verify. And we tell everyone we know: a blocked call isn’t a glitch. Sometimes, it’s a lock being picked.”

In the distance, a train horn sounded. Clara’s phone buzzed. A text from her sister: Finally got through. You okay?

He opened his laptop and pulled up a public SS7 monitoring tool—a hobbyist’s window into the phone network’s skeleton. He filtered by Clara’s prefix.
