Separate working groups have been established for the ToIP Governance Stack and the ToIP Technology Stack, with overall responsibility for approval of specifications created by both working groups falling to a Steering Committee made up of member representatives and outside industry leaders.

Two additional working groups have been chartered to serve as “foundries” for the incubation and support of ToIP-based projects at any of the four layers of the ToIP stack (Utility, Provider, Credential, Ecosystem).
