Is your telephony business running on Asterisk deployments from 5+ years ago?
While you’ve been maintaining legacy systems and applying security patches, cloud-native competitors have been capturing enterprise customers with modern APIs, seamless integrations, and carrier-grade reliability that legacy Asterisk telephony systems simply cannot match.
The gap isn’t limited to just the features; it’s about the entire fundamental architecture.
Modern telephony customers expect WebRTC browser calling, AI-powered voice analytics, omnichannel communication workflows, and real-time APIs that integrate with their business applications.
And legacy Asterisk deployments can’t deliver these capabilities without significant modernization.
You shouldn’t stop at thinking about whether to upgrade Asterisk.
You need upgrades that will position you as the next-gen Asterisk telephony system provider.
Legacy vs. Modern Systems
Why Legacy Asterisk Deployments Are Becoming Liabilities
Modern telephony customers don’t just compare your service to other traditional providers. They’re evaluating you against cloud-native platforms.
So what are the revenue opportunities that they’re using, and you’re missing?
Here are some of them:
- Video calling integration that transforms basic voice services into unified communication platforms
- SMS and messaging services that create additional per-message revenue streams
- AI voicebot integration that reduces customer support costs while creating new service offerings
- WebRTC capabilities that enable mobile and web applications, expanding your total addressable market
The liability stretches beyond dated features and losing customers. You’re also taking some compliance and security risks by not upgrading your system.
- Legacy TLS implementations that fail modern security audits
- Outdated SIP authentication that’s vulnerable to toll fraud and DDoS attacks
- Missing STIR/SHAKEN compliance that will soon be required for carrier interconnection
- Inadequate logging and monitoring that fail regulatory compliance requirements
