Media anchoring and recording
Every call is anchored and recorded from the first ring, so nothing in the conversation is lost before the agent answers.
Infrastructure
Voice AI infrastructure for reliable production calls
A voice agent is only as good as the infrastructure under it. DRING brings telephony, media edge, model routing and observability together, with active and standby paths for continuity and deployment-specific controls for data and retention.
Regions
Active and standby paths, automatic failover
Calls are anchored in an active edge path, with a standby path carrying the same media anchoring, recording, caller identity and routing configuration. Exact resilience behavior is confirmed for the deployment and carrier setup being scoped.
If the active path degrades, traffic can move to the standby path automatically. Calls already in progress on the failed leg may be affected; new calls continue on the healthy path where the configured failover supports it.
Telephony is one part of the picture. For latency fillers, model-provider failover and how a flagged call gets reviewed, see the resilience table on the technology page.

The media edge
Every call is handled at the edge, before the agent speaks
The edge is where a call is anchored, recorded, identified and routed to the right tenant, ahead of anything the agent brain does.
Caller identity
The number is looked up against your CRM before the agent picks up, so the agent already knows who is calling. See caller-identity rules for the full policy.
Barge-in and voice activity detection
Callers can interrupt the agent mid-sentence. Silence and voicemail are detected on outbound calls and handled by policy.
Calling windows and re-dial rules
Permitted hours per country and time zone, retry count, spacing and daily caps are enforced before a number is dialed, not after.
Tenant routing
Every call and message is routed to the correct tenant's agent, policies and data at the edge, before it reaches the pipeline.
Masking at source
Personal data is masked in the copy that gets stored: recordings, transcripts, reports and exports never carry it in the clear. See Voice Anonymizer.
Model layer
Swappable models, the same natural pace
The speech-to-text, language and text-to-speech models behind an agent are chosen for the language and use case, and can be swapped without a rebuild.
Swappable per agent
Speech-to-text, language model and text-to-speech providers are each selected per agent from leading vendors, and changed without touching the rest of the stack.
Turn-taking model
A dedicated model paces the conversation: real pauses, interruption handling and natural turn-taking instead of a flat, scripted read.
Deployment-specific processing
Processing location, transfer controls and data boundaries are documented and reviewed against the requirements of the deployment.
Observability
Every layer is watched, not shipped and left
Beyond the call itself, every live agent is swept weekly against its previous release, and infrastructure changes roll out in controlled stages with the previous version ready for rollback.
Health checks, alerting and the incident playbook that keep every line up are shared across telephony and infrastructure. Related: how every line is watched and rolled out.
Data and isolation
Isolated by tenant, encrypted end to end
Data belonging to one tenant is never reachable from another, and every hop, in transit and at rest, is encrypted.
Tenant isolation
Enforced across the pipeline, one of the six tested security standards.
Encryption in transit and at rest
Data is encrypted in transit with TLS 1.2 or higher, and encrypted at rest throughout the pipeline.
Retention per contract
Retention defaults apply unless your contract sets its own, with deletion available on request per number or per customer.
Full detail on data flow, retention periods and data subject rights is documented and reviewed for every deployment.

Technical flow
A call's path through the infrastructure
From the edge to the model layer, post-call analysis and your systems, every stage is instrumented.
FAQ
Infrastructure questions
What happens if an edge path has an outage?+
Traffic can move to the configured standby path automatically. Calls in progress on the failed leg may be affected; new calls continue on the healthy path where the deployment supports it.
How is processing location agreed?+
Processing location, transfers, retention and access are reviewed against the workflow, contract and applicable data requirements before production.
How are changes to an agent or a route rolled out?+
In controlled stages, with scores watched at each step and the previous version available for rollback.
Is our data isolated from other tenants?+
Yes. Your data and conversations never reach another tenant's agent, and transcripts are used only to improve your own. See security for the full detail.
