I have received several calls from this number. The caller ID shows "Phone 5" and previously I have just hung up when I found the call was recorded and was a telemarketer. This morning another call came from the number and I did not answer it, but the caller rang my line 18 times. The same thing happened last week when they rang my line 20 times. This is getting really annoying and ties up my phone line and would keep me from making a call that might be necessary. I am at a loss as to what to do.
