You don't need the 'service mgcpapp' on the dial peer for the PRI port.

Did you not paste the config download section of the 'show ccm'
output? I don't see the configuration download stats there and see a
TFTP retry of 2.  I also see 0 for all the backhail transmit/receive
stats.

I would verify your network connectivity between the MGCP interface on
the router and the Call Manager is good.

Maybe kick MGCP on the router with 'no mgcp / mgcp' in config mode.
