VON Opposes USTelecom Call Blocking Notification Proposal

Don’t adopt session initiation protocol code 603 as the industry standard for call blocking notifications, said the Voice on the Net Coalition in a letter posted Wednesday in docket 17-59 (see 2108270070). That code that USTelecom seeks “would be clumsy, at best,” VON said. It recommended the FCC require industry and standards organizations to resolve all technical issues for using SIP codes 607 and 608 by a specific deadline.
