How Film Live Streaming Hit 10k MRR in 31 Days using Signalwire
When David Plappert set out to launch Film Live Streaming, he wasn’t starting with a telecom background—he was a developer and cloud systems admin who wanted to solve a practical problem: helping churches, governments, and other organizations share their live video streams over the phone.
With just a Google Form and a simple Ruby app, David’s idea took off. In the first 31 days, Film Live Streaming went from zero to $10,000/month in recurring revenue.
The secret? Building on SignalWire.
Making Telephony Developer-Friendly
David didn’t want to spend weeks managing SIP, SBCs, and carrier interop. With SignalWire’s programmable Voice APIs and built-in telephony infrastructure, he didn’t have to. Instead, he focused on writing clean application logic—while SignalWire handled high-volume call routing and audio streaming.
“From day one, we’ve used our Ruby app to manage 10,000+ calls per second, and SignalWire has handled it without issue.”
What is RCS messaging?
Rich Communication Services (RCS) is the next generation of mobile messaging, designed to replace SMS and MMS. It supports high-quality images and video, verified sender identities, read receipts, typing indicators, and interactive elements like carousels and quick replies, all within the phone's native messaging app.
What is RCS Business Messaging (RBM)?
RCS Business Messaging (RBM) applies RCS capabilities to brand-to-consumer communication. It lets businesses message customers from a verified brand identity instead of a phone number, share rich media and documents, offer quick replies and CTAs, and handle actions like appointment confirmations and payments without the customer leaving the chat.
Is RCS replacing SMS?
RCS is positioned as the successor to SMS, but the transition is gradual. Businesses should adopt RCS where supported while keeping SMS and MMS as fallback channels for devices and networks that don't yet support it.
Does iPhone support RCS?
Yes. Apple added RCS support starting with iOS 18, with RCS Business Messaging support arriving in iOS 18.1. Combined with existing Android support, this brings RCS to the large majority of smartphones in the US.
Is RCS more effective than SMS for customer engagement?
Yes. Nearly 80% of consumers say RCS makes them more likely to engage with a brand, and RCS campaigns can achieve click-through rates up to 7x higher than SMS thanks to rich media, interactivity, and verified sender trust.
ow do businesses start sending RCS messages?
Businesses must first register an RCS agent, an approval process involving Google, aggregators, and mobile operators. From there, they can define use cases like marketing, customer service, or appointment reminders. SignalWire guides businesses through registration and campaign planning.
Which industries benefit most from RCS?
Retail, finance, and healthcare are early leaders. Retailers use RCS for in-chat purchases and product carousels, financial institutions use it for secure verified messaging and account alerts, and healthcare providers use it for appointment scheduling and reminders.
