Your assumption is incorrect: there are many H.248 IP-to-IP MG types defined, e.g. ETSI TISPAN, 3GPP, MSF or ITU-T SG11.
Such MGs may be located between two SIP devices in the IP bearer-path.
A number of H.248 statistics are defined e.g. by ETSI TS 183 018, the H.248 Ia profile V3 for border gateways.
