What version of the CatOS are you running on the 6500? Also, it's a good idea to register all the ports on the E1 blade to CallManager, even if nothing is connected to them. If you like, you can register them as conference bridges or transcoders if you don't want to register them as E1 gateways.
I had this same problem with the WS-X6608-E1/T1 card. To fix this problem I put the ports of the card in their own VLAN seperate from everything else (data / Call Manager) and set up a VLAN interface on the MSFC. I did this about a month and a half a go and have had no problems since.
