Who called from 3361234567

in the span of 20 minutes, i received a call from this number, (336)123-4567, four times.  i rejected it the first time and a voice-mail was created.  i retrieved the voice-mail and a series of 4 short beeps over a span of 8 seconds occurred.  i tried calling back, but my cell phone provider said i could not make a call to this number.  i answered the 2nd and 4th times, with the same series of 4 short beeps over a span of 8 seconds, then i hung up.

Single beep, disconnects about 10 seconds after. Called 4 times about 4 minutes apart.

Called twice 5 min a apart. Loud beep, like end of voicemail message then hangs up. You know what means..... The solicitor is calling soon after.

Do not cal!
