INOC-DBA

The INOC-DBA (Inter-Network Operations Center Dial-By-ASN) hotline phone system is a global voice telephony network that connects the network operations centers and security incident response teams of critical Internet infrastructure providers such as backbone carriers, Internet service providers, and Internet exchanges as well as critical individuals within the policy, regulatory, Internet governance, security and vendor communities.

[1] It was built by Packet Clearing House in 2001, was publicly announced at NANOG in October 2002,[2] and the secretariat function was transferred from PCH to the Brazilian CERT in 2015.

[3] INOC-DBA is a closed system, ensuring secure and authenticated communications, and uses a combination of redundant directory services and direct peer-to-peer communications between stations to create a resilient, high-survivability network.

The INOC-DBA network uses IETF-standard SIP Voice over IP protocols to ensure interoperability between thousands of users across more than 2,800 NOCs and CERTs, which use dozens of different varieties of station and switch devices.

[4] It was the first production implementation of inter-carrier SIP telephony, when voice over IP had previously consisted exclusively of H.323 gateway-to-gateway call transport.
