                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25065
             Project: Asterisk
          Issue Type: Bug
      Security Level: None

>From all appearances, SRTP appears to function except over time, calls begin failing. Temp solution is to restart phone and resume calls after registration.
