Only half of the T1 channels came up

I have a cisco 2811 router connected to an Avaya PBX. The cisco gateway is an MGCP gateway in Call Manager 5.1. I recently upgraded the router IOS from 12.4(15)T to 12.4(24)T. After the upgrade only half of the channels on the T1 would come up. The D channel and half the B channels were working fine.

Yes there are. It was working before the IOS upgrade.
