Exemption rules
47 CFR Sec. 64.6304(d) – extension of implementation deadline for non-IP networks Sierra Telephone has implemented STIR/SHAKEN in the IP portions of our network that support SIP calls, but that there are still portions of the network that are TDM that are unable to support STIR/SHAKEN. Under the FCC’s terminology, that would be considered “partial implementation”, where its technically feasible.
