TE210P PRI fails with Dahdi

We recently upgraded from Asterisk 1.4 to 1.6. As the result, the PRI failed and Dahdi will no longer accept the signaling type ‘PRI_cpe’ which worked previously. The PRI is lineside from an Avaya CM 3 PBX to the Asterisk using a TE210P. Has anyone run into this problem? We tried changing the trunk signaling to automatic but that failed too.

could be a case issue try “pri_cpe” instead of “PRI_cpe”
