Explanation

MGCP and SCCP gateways are controlled endpoints: Cisco Unified CM directly manages their call signaling, and dial peers on the gateway are not required for PSTN routing-CUCM pushes the routing logic. H.323 and SIP gateways, by contrast, operate as peer-to-peer VoIP devices that rely on locally configured dial peers to route calls. On H.323 and SIP gateways, administrators must manually define dial peers specifying destination patterns, codec preferences, and the IP address of the call agent or PSTN trunk. Without this manual configuration, those gateways cannot independently route PSTN calls.
