Kubernetes + VoIP: CelloIP's Unique Specialisation
Most Kubernetes engineers have never deployed a production VoIP workload on K8s. SIP signalling requires sticky sessions (StatefulSets), RTP media requires hostNetwork or precise LoadBalancer configuration for the UDP port range, and codec transcoding workloads have specific CPU pinning requirements.
CelloIP engineers have done this in production — Asterisk clusters on EKS, FreeSWITCH on GKE, Kamailio SIP proxy on Hetzner K3s, and LiveKit self-hosted on bare-metal K8s. If your project involves VoIP workloads on Kubernetes, this combination of expertise is extremely rare outside of CelloIP.
Discuss VoIP on KubernetesAsterisk StatefulSets
Sticky SIP sessions, persistent volume for voicemail/recording, Kubernetes-native HA
FreeSWITCH on K8s
High-density media containers, ESL-based call routing, horizontal pod autoscaling by CPS
Kamailio / OpenSIPS SBC
SIP edge proxy on K8s with shared Redis for state, horizontal scaling, HPA by registration load
LiveKit Self-Hosted K8s
LiveKit server on Kubernetes, integrated TURN, Ingress for WebSocket, Prometheus metrics
Why Hire Kubernetes Engineers from CelloIP?
Full-time staff — not contractors
Every engineer is a full-time CelloIP employee with deep institutional knowledge. No marketplace churn or contractor disappearing mid-project.
VoIP + K8s specialisation
Unique expertise in running SIP, RTP, and WebRTC workloads on Kubernetes — extremely rare outside of specialised VoIP infrastructure teams.
$25/hr — 70% less than US rates
Senior K8s architects at $35–$55/hr. US equivalent: $120–$200/hr. Same seniority, same production track record, fraction of the cost.
48-hour onboarding
NDA signed Day 1. Access provisioned in hours. Most engineers are contributing code and K8s YAML by end of Day 1.
Full IP ownership
Every Helm chart, Terraform module, ArgoCD app, and Kubernetes manifest you pay for belongs to you — forever, fully.
Timezone overlap
India IST (UTC+5:30) overlaps with US morning (5:30–9:30 AM EST) and all of EU business hours. Daily standups, Slack, and async-first workflow.
Frequently Asked Questions
How much does it cost to hire a Kubernetes developer?
CelloIP's Kubernetes engineers start from $25/hr for mid-level and $35–$55/hr for senior K8s architects — 60–70% less than US/UK rates. All engagements include NDA Day 1, 48-hour onboarding, and full IP ownership.
Can Asterisk and FreeSWITCH run on Kubernetes?
Yes. Asterisk uses StatefulSets for sticky SIP sessions, hostNetwork or a SIP LoadBalancer for RTP, and a Kamailio/OpenSIPS SBC at the edge. FreeSWITCH containerises cleanly for high-density media. CelloIP runs production VoIP-on-K8s deployments handling millions of minutes monthly.
What Kubernetes tools do your engineers specialise in?
EKS/GKE/AKS/self-hosted K8s setup, Helm chart development, ArgoCD/Flux GitOps, Terraform IaC, Prometheus/Grafana observability, Istio/Linkerd service mesh, cert-manager TLS, KEDA event-driven scaling, and VoIP-specific K8s workload patterns.
How quickly can a Kubernetes engineer start?
48 hours. NDA Day 1, access provisioned in hours, contributing to your K8s infrastructure by the end of Day 1. No recruitment process — interview one engineer, agree, they start.
Do you manage ongoing clusters or only set them up?
Both. Fixed-price initial setup projects and ongoing dedicated engineer engagements for cluster management, upgrades, scaling, incident response, and new workload deployments. Many clients start with setup then keep a part-time K8s engineer for ongoing ops.
What is the difference between a Kubernetes developer and a DevOps engineer?
A K8s developer specialises in K8s workload design — Helm charts, operators, custom controllers, and YAML for complex stateful apps. A DevOps engineer has broader CI/CD, IaC, and cloud networking scope. For K8s-heavy projects, a K8s specialist gets to production faster than a generalist.
