Can you share a screenshot of the error?

You can try the following things getting into packet captures and traces.

1) Remove the IPMA config from one 7970 and reconfigure it. It includes unsubscribing the ipma service and resubscribing it.

2) Restart of IPMA and CTI services

Please provide details like cucm and phone firmware versions so that any known issues / defects can be checked.
