If you have a TE2xxp card (TE210 TE205 or TE220) you should update your DAHDI version to latest trunk as there was a bug in that driver which would have caused an issue similar to this. Otherwise, you might check with your telco to check if the link has been turned up. Matthew Fredrickson Digium, Inc.
