SMS API for VoIP Providers
Send verification codes, missed call alerts and service notifications to your customers with a simple REST API and reliable Australian routes.
How VoIP providers use SMS
A missed call with no follow-up is a lost customer for whoever's using your phone system, and a login that needs a second factor is where most support tickets start. VoIP providers use SMS to turn a missed call into an instant text alert, verify logins to a customer portal or app, and let customers know the moment there's a service issue instead of waiting for them to notice.
Mobile Message sends from 1.6¢ per message with no monthly fees or contracts, so adding SMS notifications to your platform costs a fraction of building your own gateway. Integrate over a REST API or webhooks to trigger alerts straight from your call platform, and let customers reply to a two-way number that lands in a shared inbox your support team can manage.
Missed call to SMS alerts
Text a customer's team the moment a call is missed, with the caller's number, so a lead or a customer enquiry doesn't just disappear.
Verification codes and 2FA
Secure logins to your customer portal or softphone app with a one-time code, without asking customers to install another authenticator.
Service status alerts
Let affected customers know as soon as an outage or maintenance window is detected, before they start raising support tickets.
Voicemail and callback notifications
Send a text the moment a voicemail is left, or confirm a callback request has been logged, so nothing sits unheard in an inbox.
