If any errors are encountered during the Ingress and Egress policy application, or other violations of RFC3264 occur, the call is rejected. If O2 does not contain any enabled m= lines at the conclusion of the initial call setup, the call is rejected. If O2 does not contain any enabled m= lines at the conclusion of a reINVITE, the reINVITE is rejected and the call reverts back to its previous state.
