Verification that SMS is operational

We recently had some disruption with both of our sms notification methods: Twilio and a Raven RV50. I am looking for an automated way for Ignition to alert me when either of my sms notification methods fails to send. I'm thinking about scheduling a daily recurring sms that requires an ack and if the ack is not received in 60 secs, it would alarm out (via other means) that sms is down. I don't yet know how to go about implementing this though. Has anyone else been down this road (even if it was for just one sms notification method) and did you do something similar? I would be curious to know what others have done before I go down this road myself. Thanks in advance for your input.

I've done similar daily test alarms to test functionality, however I'm following this because a more robust way to know if the system is operational would be ideal.
