Self-Hosted Telephony & SIP
Asterisk, SIP and carrier integration we build and run ourselves — for when a resold dialer will not meet your cost, control or compliance requirements.
3–6 weeks depending on carrier setup
Most AI voice vendors resell someone else’s telephony, which caps what they can control and what you pay. We build the telephony layer too: Asterisk with PJSIP, ARI-driven call control, per-DID carrier endpoints, and call detail records you own. It matters when you have many numbers, per-number caller ID requirements, high call volumes, or data that cannot leave your infrastructure.
What this solves
- Per-minute SaaS telephony costs that scale badly with volume
- Outbound calls rejected for presenting a caller ID on the wrong trunk
- No control over call routing, recording or retention
- Call data leaving your infrastructure when it must not
What you get
- Asterisk and PJSIP configuration rendered per DID and carrier
- ARI-based programmatic call origination and control
- Carrier and SIP trunk integration
- Call detail records and recordings retained on your terms
- Health monitoring of SIP registration state
- Deployment on your infrastructure or ours
