I have the burner app on my phone with three lines. Two of the lines are currently being forwarded to another phone of mine. I have setup a custom voicemail greeting for these two forwarded lines - however when ever I call the burner number from my cell phone (with burner downloaded) - it rings on my second phone but eventually goes to that phones standard voicemail, not the custom one saved through the app.
This is actually normal behavior on a forward, since you have successfully forwarded the line outside of our app. The only way to stop it from getting to someone else's voicemail is to not active the forward, since forwarding transfers the call to the other line completely.
With SMS, as long as you follow the command prompts in the SMS, we can re-route it back through the Burner, but the call forwarding is standard. Hope this was helpful, let us know if you need anything else!
