[cisco-voip] Upgrade from 2801 to 2911

[Guilherme Loch Waltrick Góes]

Hi guys,

We just upgraded a site that was running a 2801 with a ISDN PRI link
to a PBX to a 2911 with the exact same setup. The setup with the 2801
was running just fine. The problem is, running with the same config on
the 2911 we keep getting MANY Line Code Violations and other assorted
errors, the calls are very noisy and sometimes we can't place the
calls from this site to the other sites.

Did anyone experienced the same situation? How can a solve this problem?

Bellow is some info about this router:
