Is a one-ring call something blocked by Nomorobo?

I do subscribe to Nomo and simultaneous ring is enabled.   Maybe it was my misunderstanding but I thought that if you heard your phone ring twice (unless the caller just hung up) the call was being blocked by Nomo.   Lately, I'm getting a lot of calls where the phone only rings once.

With SimRing, both your phone and Nomo will each get a ring.  After Nomo gets its 1st ring, it will screen, lookup and send a block message (if applicable) back to Cox before the 2nd ring.

If this process works as designed, neither your phone or Nomo will get a 2nd ring.

If your phone was ringing twice and then the "caller" was hanging up, either Nomo or Cox was impeding the process.  Sometimes, however, some malcontents will war-dial blocks of numbers to harvest a list of actually assigned and ring-able phones.  They're just building a list for efficient telemarketing.

Thanks for the explanation; it's good to see that Nomo is actually blocking calls.   Appreciated!
