Complete 10DLC with your carrier before using SMSable.
Configuring your VoIP.ms account with SMSable is pretty simple and should only take a few minutes.
Set the inbound SMS/MMS URL to:
https://inbound.smsable.app/receive?provider=voipms&to={TO}&from={FROM}&msg={MESSAGE}&media={MEDIA}&id={ID}
You can optionally enable URL Retry. That can occasionally create duplicate inbound messages.
Private label customers replace inbound.smsable.app with their hostname. Enter VoIP.ms API credentials and DID in your SMSable profile.
That’s it, you should be able to send and receive messages!
