Forget about messing around with apps. There’s a powerful voicemail handling system built into nearly every big carrier today — and that system almost always includes a system for recording a voice message and sending it directly without ringing the target phone. I will walk you through the process of doing this on Straight Talk (since that happens to be my carrier) but most carriers will have similar systems.
On the app, click on the "Sound" icon at the lower left part of the tool and select "Microphone." Then, open your voicemail service on your phone and play the voice message. The online audio recorder then clicks the "Record" button on the audio recorder while the voicemail is playing. If you are recording using an external mic, make sure that your phone is on the loudspeaker and pointed at the mic.

So make sure you connect with them to make sure you have it. If you don't see that play on the record and that way you'll just have to basically record and use a different device to call them yourself, to hear your voicemail. I hope you found this useful. Please give it a thumbs up and subscribe to this channel for easy-to-follow, how-to videos, and tech videos, just like this one and I'll catch you next time. Thanks for watching.
Note that the secretary has asked for the reason for calling so she can prioritize the patients who need the most help. She’s also keeping it short and to the point.
