<div dir="ltr">I've noticed in the SIP responses coming through our termination LCR a few that mention calls blocked due to DNIS listed on the Do Not Call Registry. I've also seen DNC blocking mentioned in other robocall blocking contexts. I understand the benefit in doing this, but I don't understand how carriers are able to use the DNC this way. Is there some exemption to the DNC rules that permit this use case? The rules as they are written on the DNC website indicate that I would need an active Subscriber Account Number from each of my clients in order to perform any kind of DNC filtering, with controls to ensure each client is only dipping the area codes they are paying for. Is using the DNC across an entire network for robocall blocking actually a misuse of the DNC?<br><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><span><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:"Proxima Nova",sans-serif;color:rgb(0,0,0);background-color:transparent;font-weight:800;vertical-align:baseline;white-space:pre-wrap"><br></span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:"Proxima Nova",sans-serif;color:rgb(0,0,0);background-color:transparent;font-weight:800;vertical-align:baseline;white-space:pre-wrap"><br></span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:"Proxima Nova",sans-serif;color:rgb(0,0,0);background-color:transparent;font-weight:800;vertical-align:baseline;white-space:pre-wrap">Calvin Ellison</span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:"Proxima Nova",sans-serif;color:rgb(0,0,0);background-color:transparent;vertical-align:baseline;white-space:pre-wrap">Systems Architect</span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:"Proxima Nova",sans-serif;color:rgb(0,0,0);background-color:transparent;vertical-align:baseline;white-space:pre-wrap"><a href="mailto:calvin.ellison@voxox.com" target="_blank">calvin.ellison@voxox.com</a></span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:"Proxima Nova",sans-serif;color:rgb(0,0,0);background-color:transparent;vertical-align:baseline;white-space:pre-wrap">+1 (213) 285-0555</span><span style="font-size:2.25pt;font-family:"Proxima Nova",sans-serif;color:rgb(0,0,0);background-color:transparent;vertical-align:baseline;white-space:pre-wrap"><br><br></span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><a href="http://voxox.com" target="_blank"><span style="font-size:10pt;font-family:"Proxima Nova",sans-serif;color:rgb(17,85,204);background-color:transparent;vertical-align:baseline;white-space:pre-wrap"><span style="border:none;display:inline-block;overflow:hidden;width:139px;height:53px"><img src="https://lh5.googleusercontent.com/IpUfF3j5Y4T9UmEfLISsHXhgSenc131vheivxwdo6oyzyT1i5KfVnK8cftA1Qx-APliNpMTLx5PUOZ6k1lXHgMZvDXTXKkOWDpmXMlUcmsoKBZQIE_wip4sS8XMtdryakordMboW" width="139" height="53" style="margin-left:0px;margin-top:0px"></span></span></a></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><a href="https://www.facebook.com/VOXOX/" target="_blank"><span style="font-size:12pt;font-family:"Proxima Nova",sans-serif;color:rgb(17,85,204);background-color:transparent;vertical-align:baseline;white-space:pre-wrap"><span style="border:none;display:inline-block;overflow:hidden;width:27px;height:27px"><img src="https://lh6.googleusercontent.com/qS_cwPUkKDN7UEAMffT5cjE1qN41OWxwS8HKu2DZi8R9OfYZCrdVxxPsyJy_SOaTDjWHjPAsBAzGnrgiSgrqDFWQKoi1HAdYUldZOtUQY_2EH0FC7M67fPko4xEmw7yfwiIpnRIF" width="27" height="27" style="margin-left:0px;margin-top:0px"></span></span></a><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;vertical-align:baseline;white-space:pre-wrap"> </span><a href="https://www.instagram.com/voxoxofficial/" target="_blank"><span style="font-size:12pt;font-family:"Proxima Nova",sans-serif;color:rgb(17,85,204);background-color:transparent;vertical-align:baseline;white-space:pre-wrap"><span style="border:none;display:inline-block;overflow:hidden;width:26px;height:26px"><img src="https://lh3.googleusercontent.com/AFGDGW3w1Yco24kAphoI6UZW170z44YjZpLZ0rHGRfCDNyctuD4DkIYooDbxEoJxrv0NQ4TswSWA4k0FPOD6w5v_ZFadQmeoXHhP1rgeZXdoLV7n-1PGxYhi31pbte1GHYwURny8" width="26" height="26" style="margin-left:0px;margin-top:0px"></span></span></a><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;vertical-align:baseline;white-space:pre-wrap"> </span><a href="https://www.linkedin.com/company/3573541/admin/" target="_blank"><span style="font-s
