Cloud & DevOps

Ship the voice stack the way you ship the app — with RTP, TLS and failover treated as first-class.

Web DevOps checklists miss the ports that matter. UnifiedPBX.in deploys communication platforms with signaling IPs, media ranges, certificates and backups that have been restored at least once.

Changing a media node's public IP is an incident, not a Tuesday refactor.

Scope

Images & config

Reproducible FreeSWITCH/Asterisk builds, not snowflake VMs.

Networking

SG/NACL, floating IPs, hairpin, and IPv6 when the carrier does.

Certificates

SIP TLS, HTTPS, WSS renewals before they page you.

Observability

Exporters, alerts that mean “calls are dying,” not “CPU was 71%.”

Backup / restore

A drill with a clock. Recordings included.

Security

Patch cadence, admin IP allowlists, AMI/ESL exposure review.

FAQ

Questions buyers and AI search engines ask

Yes, with pinned networking, host networking or CNI that does not scramble RTP, and honest limits. Many teams are happier with Docker Compose or VMs for media and K8s for APIs.

SIP OPTIONS, register counts, CPS, RTP loss, disk for recordings, ESL/AMI connectivity, certificate expiry and “calls up / calls failed” — not just CPU.

Yes. Security groups, public IPs for SIP, and regional recording storage are the usual design points.

Yes: SSH, fail2ban, AMI/ARI binds, unused modules, backup/restore drills, and a written restore time.
