Summary •

•

•

•

•

•

MGCP gateway configuration depends on router model and used VICs. Configure IOS MGCP gateways to pull the configuration from CallManager to reduce manual configuration efforts. Debug and show commands can be used to verify the MGCP gateway and endpoint status. H.323 gateway is generic and does not depend on used IOS gateway. Configure IOS H.323 gateways with correct dial-peers to interact with CallManager. Debug commands can be used to verify dial-peer matching and H.225 signalling.
