In most/all cases, the callers are large organizations… hospitals, pharmacies, insurance companies, etc. It appears many of the large companies haven’t bothered to SHAKEN sign their calls nor manage their reputations via <a href="https://calleridreputation.com">https://calleridreputation.com</a>, <a href="https://calltransparency.com">https://calltransparency.com</a>, etc. Many use a single TN for all their outbound calls. ;-(</span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"><span style="color:#1f497d">Our strong suspicion is that because large carriers have whitelisted the calling TNs and the importance of valid calls, spoofers are hot to use them and the reputation databases reflect that.</span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"><span style="color:#1f497d">Problem for us, of course, is that our customers want to receive calls from the real organizations but we have no way of determining which calls are real and which are not. Only the TN reputation score from industry databases and call headers are available. </span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"><span style="color:#1f497d">Just curious what others are doing and seeing “in the wild”. Is playing the whack-a-mole whitelisting game really the best solution? An alternative idea of letting all bad reputation calls through and simply marking them as ‘spammy’, regardless of score, seems like a cop-out.</span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"><span style="color:#1f497d">-Joel</span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"><i><span style="font-size:10.0pt;color:#595959"> </span></i><span style="color:#1f497d"></span></p><p class="MsoNormal"><i><span style="font-size:10.0pt;color:#595959">Joel Stalder</span></i><span style="color:#1f497d"></span></p><p class="MsoNormal"><i><span style="font-size:10.0pt;color:#595959">Director, North American Network Operations</span></i><span style="color:#1f497d"></span></p><p class="MsoNormal"><i><span style="font-size:10.0pt;color:#595959">+1.408.400.3830</span></i><span style="color:#1f497d"></span></p><p class="MsoNormal"><span style="color:#1f497d"><img border="0" width="150" height="40" style="width:1.5625in;height:.4166in" id="Picture_x0020_1" src="cid:image001.jpg@01D7E059.CB05B8E0" alt="Panterra_newest_logo150"></span></p><p class="MsoNormal"><i><span style="font-size:10.0pt;color:#595959">"The Unified Cloud Service Provider"</span></i><span style="color:#1f497d"></span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"> </p></div></body></html>
