Open-Source Platforms
Asterisk Development
Asterisk is the open-source PBX that powers millions of phone systems — but shipping a production-grade Asterisk platform takes more than apt-get. We design dialplans that scale beyond the goto/macro trap, build AGI and ARI applications for CRM and billing integration, tune RTP and SIP stack performance, and deliver Asterisk clusters that survive trunk outages and traffic spikes. Whether you're building a hosted PBX, a wholesale termination platform, or a contact center, we treat Asterisk the way a systems engineer treats any critical infrastructure: instrumented, version-controlled, and load-tested before it carries a single real call.
Who it's for
- ITSPs launching retail or wholesale voice platforms on Asterisk
- Enterprises migrating from legacy Avaya, Cisco, or Mitel to open-source
- Contact centers outgrowing stock Vicidial or FreePBX deployments
- Product teams embedding voice into their SaaS application
Our approach
- 1Audit the existing dialplan — surface goto loops, duplicated logic, and N+1 variable lookups
- 2Refactor to AEL or ARI where logic exceeds what extensions.conf can cleanly express
- 3Instrument call flow with CDR, CEL, and Prometheus exporters for real observability
- 4Load-test at 2× projected peak CPS using SIPp scenarios before production cutover
- 5Document handoff so your ops team can debug without calling us at 3 a.m.
