This solution applies to all Barracuda Phone Systems running firmware version 2.5.003 and later.
Firmware release 2.5.003 added add series of ping tests in order to proactively alert you to connectivity issues that will negatively affect your Barracuda Phone System's ability to handle calls.
The tests are run every 5 minutes, and include a short series of ICMP Echo Requests (also called pings) to the following destinations:
- The configured Default Gateway
- Both configured DNS Servers
- The Hostname or IP Address listed in each of the configured SIP Provider
