Yup, TURN servers could be provided by local network, access network, an application service provider or a third party provider. The ICE agent also needs to use server preference to prioritize the relayed candidates learnt from different administrative domains. For the enterprise use case discussed in http://tools.ietf.org/html/draft-ietf-rtcweb-use-cases-and-requirements-14#section-3.3.5 TURN server provided by the local network should have the highest priority.
