Use Case
AI-Ready Communications
Prepare SIP and voice infrastructure for secure interaction with AI agents and cloud communications platforms.
Products to compare
A starting point for your project. Review the model data sheet before ordering.
Sentinel 400 SBC & Gateway
A modular voice edge for sites with mixed telephony interfaces.
- Selection criterion

- Selection criterion
- Supported hosting environment, CPU resources and licensed capacity.
CALL-PATH SCHEMATIC
Trace the ai-ready communications path end to end.
Every device and service is part of a live operating workflow. The diagram makes the translation point, trust boundary and acceptance target visible.
NO PUBLIC INTERNET REQUIRED
Private LAN / isolated IP network
Local phones, a local IP PBX, Mediatrix gateways and Sentinel can exchange SIP calls entirely inside the organization. The voice path can remain on a private LAN, VLAN, campus network or isolated operational network.
REQUIRED FOR THE CLOUD AI SERVICE
Controlled cloud connection
The AI or CCaaS service needs an external connection. Sentinel keeps that third-party service outside the trusted internal voice domain and exposes only approved SIP routes.
PRIVATE CUSTOMER NETWORK
Carrier network
Supplies reachability to public numbers.
People & agents
Continue to use the approved enterprise communications environment.
Observability
Correlates call records, policy events and service behavior.

INTERNALIndependent local pathLocal PBX, gateways and extensions can keep communicating even though the cloud route is shown separately.
CONTROLLED EDGE
SECURE EDGE
Controlled SIP boundary
Keeps experiments and third-party services outside the trusted production domain.
EXTERNAL SERVICE NETWORK
AI communications service
Consumes or originates voice through defined SIP interfaces.
Business systems
CRM, contact-center and workflow services receive controlled interactions.

READING THE DIAGRAM
Follow one call from the cloud to the telephone network
- Cloud voice platform
- Hosts communications services such as Microsoft Teams Phone or CCaaS outside the customer site.
- Sentinel SBC
- Secures and normalizes SIP between voice domains, controls media and routing, and hides the internal network.
- SIP carrier
- Connects the organization to the public telephone network and supplies telephone numbers and external call routes.
- PBX or call server
- Controls extensions, features and call routing. It may run on-site, in a data center or as a hosted service.
Use-case model — field validation remains mandatory for endpoints, carriers and safety-related workflows.
VALIDATION MATRIX
The checks that prevent a silent failure after cutover.
A ai-ready communications design should answer each question before rollout, not after the first incident.
Safety, emergency, alarm and regulated services require approval from the responsible authority and service provider for the actual deployment.| Validation layer | Question to answer | Evidence to collect | Owner |
|---|---|---|---|
| Endpoint | Does the real device behave correctly over the new path? | Dialing, media and feature test | Customer / integrator |
| Network | Are latency, jitter, NAT and QoS controlled? | Capture and quality baseline | Network team |
| Service | Does the carrier support the required call or data behavior? | Carrier-accepted test result | Carrier / service owner |
| Failure | What happens during power, WAN or platform loss? | Failover and recovery test | Operations |
| Lifecycle | Who owns updates, certificates, backups and escalation? | Approved runbook and entitlement | Service owner |
FREQUENTLY ASKED
What to know before the next step.
The most common risk is assuming endpoint, carrier or network behavior instead of validating it in the actual call path.
Use a repeatable reference architecture, but confirm site-specific power, WAN, interfaces, endpoints, local routing and operational constraints.
The pilot should prove real workflows, not only dial tone: features, media quality, exceptional routes, failover, monitoring and recovery.
