You can troubleshoot network issues from the public switched telephone network (PSTN) to the Mediation Server as follows:
- Ping the IP address of the PSTN gateway from the Mediation
Server. If there is no answer, there is a connectivity issue.
- Check the event log of the Mediation Server for error messages
that could be relevant. For details about relevant Office
Communications Server events, see
Enterprise Voice-Related Events.
- Start Performance Monitor and add the
Mediation Server – Inbound Callsobject. This enables you to
view the Mediation Server counter values. For details about
relevant Office Communications Server performance counters, see
Enterprise Voice-Related Performance Counters.
