Security & Reliability

The isolation the admin UI claims — on SIP, recordings, APIs, secrets and the failover path.

Enterprise buyers do not hire a “SIP developer” and hope security appears later. UnifiedPBX.in treats TLS, SRTP, identity, tenant isolation, fraud, backup and HA as part of the same architecture as the dialplan.

2026 buying brief

Who this is for

Teams selling multi-tenant PBX, CCaaS or CRM-on-voice who cannot answer “can tenant A fetch tenant B’s recordings?”

What you get

A review and a fix path for signaling crypto, authz, secrets, fraud and the restore drill — not a generic ISO checklist.

If the tenant id is optional on a recording URL, the isolation slide is fiction.

What we harden

Signaling & media

SIP TLS, SRTP, no leftover UDP ‘for compatibility’ on the public edge.

Identity

Authentication, RBAC, tenant roles, admin vs agent vs API tokens.

Isolation tests

Automated checks that tenant A cannot read tenant B presence or CDR.

Secrets

No SIP passwords in localStorage, no AMI on 0.0.0.0, rotated tokens.

Fraud controls

Destination locks, CPS, sudden-international alerts.

Survive it

Backup, restore, HA and the runbook when the primary SIP box dies.

FAQ

Questions buyers and AI search engines ask

No. SIP TLS, SRTP, recording URLs, AMI/ESL exposure, tenant-scoped queries and who can impersonate an agent are the actual review. A lock icon on nginx is table stakes.

When the product needs admin / supervisor / agent / API roles keyed to a tenant. We do not drop in a generic IAM product and call the PBX done.

CPS limits, destination policy, account-code discipline and alerts when a trunk starts behaving like a scanned box. Policy lives next to routing, not in a slide.

Possible for some control planes; media and registrations need an honest failover story. We will say when a single VM is the risk.
