📞 Strengthening SIP Security Starts With Proper Certificate Setup
Your SIP infrastructure is the backbone of your communication network — and in a world where spoofing and fraud keep evolving, SIP alone isn’t enough. That’s why telecom operators are turning to STIR/SHAKEN certificates to secure call identity and maintain FCC compliance. But to get authentication right, you need certificates set up correctly inside your SIP environment.
Peeringhub.io makes this entire journey smooth, fast, and intuitive. Whether you’re using FreeSWITCH, Asterisk, Kamailio, OpenSIPS, or a custom SIP solution, integrating Peeringhub’s certificates into your infrastructure is a straightforward process when you know the essentials.
Let’s walk through how to make it happen — clean, simple, and reliable.
🔐 1. Generate Your Certificate Using Peeringhub.io
Start by logging into your Peeringhub Web UI or triggering issuance through the ACME API. Once you request your STIR/SHAKEN certificate:
Peeringhub completes the FCC/STI-PA validation
Your certificate is issued instantly
Keys and certs are stored securely in your Peeringhub repository
This gives you everything needed to authenticate outbound SIP calls right from your servers.
⚙️ 2. Download the Certificate Bundle
Your SIP infrastructure typically needs:
The private key
The public certificate
The certificate chain (CA bundle)
Peeringhub provides all of these, securely downloadable from your portal. They’re packaged cleanly so engineers can import them directly into their SIP servers without friction.
🧩 3. Install Certificates in Your SIP Server
How you import them depends on your SIP platform:
For FreeSWITCH:
Place the certificate bundle into the TLS directory and reference it in your vars.xml or profile configuration.
For Asterisk:
Load your certificate and private key into /etc/asterisk/keys/ and update your pjsip.conf for TLS/SIP signaling.
For Kamailio/OpenSIPS:
Import the cert/key pair into your TLS configuration block and ensure permissions allow SIP processes to access the files.
Regardless of the platform, the main goal is the same: 👉 your SIP server must be able to sign and verify calls using the Peeringhub-issued STIR/SHAKEN certificate.
🔄 4. Configure Identity Header Signing
Once the certificates are installed:
Enable SIP Identity header generation
Configure your server to sign outbound calls using the private key
Ensure the attestation level (A, B, C) matches your business model
Peeringhub certificates allow your server to generate verified identity tokens — the core of STIR/SHAKEN authentication.
🌐 5. Test Authentication Across Your Network
Before going live, run test calls to verify:
The Identity header is present
The signature validates properly
The certificate chain is trusted by downstream carriers
No TLS errors or permission issues exist
Most SIP platforms include debug tools that show identity signing in real time. If any issues arise, Peeringhub’s support team can step in to help.
🔒 6. Automate Renewals to Avoid Expired Certificates
Certificates expire — and missing a renewal can disrupt call authentication instantly. To prevent downtime:
Use Peeringhub’s ACME API for automatic renewals
Or upload new certificates manually through the Web UI when notified
Ensure your SIP server reloads certificates without restarting the entire system
Automation ensures you stay compliant without manual maintenance headaches.
📈 7. Monitor Trust Status and Performance
Peeringhub offers clear dashboards showing:
Certificate validity
Expiration timers
Usage metrics
Authentication status
These insights help your engineering team spot issues early, maintain security, and ensure every call remains verifiable and trusted.
