Lately I've been getting a lot of calls where the phone only rings once; it started happening about a month ago. Is this Nomorobo blocking calls (that would be nice!). I thought when Nomorobo blocked a call it would ring twice.
Do you subscribe to Nomo and have Simultaneous Ring enabled? If so, Nomo needs 1 ring during Simultaneous Ring to screen and decide to block a call.
The "ring twice" rule is the "time" a phone receives Caller ID info.
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!
