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.
