also i have 2 BRI , do  i need to use Trunkgroup ? or do i need to 2 dial peer for  2 bri voice port. 

but in debug voip ccapi inout , showing call is going to desired dial-peer,

For MGCP gateway dial-peers will not be used for call routing.For an outbound call from CUCM to this gateway please make sure that this gateway is added in the Route list of the route pattern through which the call goes out via this gateway. If the call fails then get "debug mgcp packets" for a test call from the gateway.

For incoming calls just need to make sure that the CSS defined on Incoming calls information on the gateway BRI page has access to the partitions of the IP phone DN that is being called from outside.

You can use the following as a reference
