Poor call quality after upgrade to 4.1.3

We recently upgraded our 2 CCM clusters to 4.1.3. Now we have poor voice quality on local calls. Clipping, cut outs, dead air. Everything was fine before the upgrade.

3545 Router:c3745-ipvoice-mz.123-14.T5.bin

Local PSTN connection PRI to DMS-100

7960 firmware version P00307020300

Has anyone else seen this issue after an upgrade?
