CallManager 8.0 caller id issues

We have Call Manager 8.0, and we have FXO ports with an MGCP 2821 gateway. The caller ID will work for one call, and then go back to displaying unknown name and number. If we reset the gateway, it will display the caller ID for one call again, but only the first call. We have tried changing the ring settings, etc. thinking it was a delay problem, but that did not work.

This should be a simple fix. Try the following

Do a "shut"/"no shut" on the voiceport 0/0/0
