AudioCodes SBC's - Is there a way to monitor the SIP trunk status via SolarWinds?

Have you tried to find the status with SNMP? Gateway-SBC SNMP Reference Guide Version 7.4 (audiocodes.com) I prefer to avoid SNMP traps (though it looks like that is an option), and they have alerts as a table even if the SIP trunk itself isn't there. It looks like what you need is there. 

There are a number of ways to pull that in once you know what you want, here are 2

How to Create a Universal Device Poller (UnDP) in NPM (solarwinds.com)
Monitor SNMP using SAM (solarwinds.com)

The SAM template I find pretty simple, but people do get confused on UnDP, I recommend hitting the training in the customer portal if the article doesn't help.
