'Sunset' SIP Code 603 Once 607, 608 are Standardized: NORC

The National Opinion Research Center asked the FCC to require that voice service providers use session initiation protocol 607 or 608 for call blocking analytics, in meetings with Wireline and Consumer and Governmental Affairs staff (see 2202010031). There are "no guarantees that SIP 603+ standardization will not face the same implementation delays as those the telephone industry has claimed would plague SIP Code 607/608 standardization," the group said, per an ex parte posted Tuesday in docket 17-59. NORC asked the FCC to "completely ... sunset" SIP code 603's use once codes 607 and 608 are fully standardized.
