I have been using an Obi + GV for a few years, using the GV number as my home phone number. In the past, I never had a problem with telemarketing calls. Spam filtering was not enabled in the GV settings because I didn't needed it. My spam folder in GV was empty, so I don't think GV was automatically doing any filtering.
A few weeks ago I signed up with Vestalink. Vestalink has replaced GV as SP1 in my Obi. My GV number is now forwarded to Vestalink (i.e. forwarding is configured in GV, I did not port the GV number to Vestalink). Vestalink is also setup to spoof caller ID and report my GV number.
Shortly after I subscribed to Vestalink I started getting multiple telemarketing calls per day to my GV number (the spam calls are coming in via GV, not via my new Vestalink number).
I don't want to make any false accusations here, but the timing is very suspicions. It seems like my GV number got revealed to telemarketers by either GV or Vestalink after I made the changes described above. I have not done anything else new or unusual on my end.
Has anyone else experienced this after switching to Vestalink or another non-GV provider?
I've not had that problem but I wonder how you used your GV # with them. I have it both for contact and billing. I can't imagine where else they would have the number documented.
I have been a customer for about 10 weeks.
