Protocol & Infrastructure
VoIP Consulting
Sometimes you don't need us to build — you need us to review what you've got, evaluate a vendor's pitch, or be on-call for the next time things break. Our consulting engagements range from one-week architecture audits (here's what's fragile, here's what's wasteful, here's what's missing) to ongoing retainers where senior VoIP engineers are reachable in under 30 minutes during your business hours. We also help teams evaluate vendors — Cisco vs FreeSWITCH migration, Oracle ACME vs Kamailio SBC, LiveKit vs Twilio — with the objectivity that comes from not selling any of them.
Who it's for
- Teams inheriting a voice platform and wanting a second opinion on its shape
- CTOs evaluating vendor pitches for a voice infrastructure decision
- Operators who need expert on-call without hiring a full VoIP team
- Organizations where the one person who knew the SIP stack just left
Our approach
- 1Start with a pcap and the architecture diagram — most issues are visible in both
- 2Review signaling, media, security, observability, and cost independently
- 3Prioritize findings by blast radius, not by severity taxonomy
- 4Deliver findings as a prioritized action plan, not a 100-page report
- 5Stay available post-engagement for questions — we charge per answer, not per hour
