SLA, security, deployment, and integrations are scoped around your stack. The important parts are agreed before production.
SLA
Self-host
SIP
Custom credit volumes
Your ops team sets the monthly ceiling. No overage surprises, no forced plan upgrades mid-campaign.
Dedicated account manager
One person who knows your stack, your SLA, and your team. Reachable — not queued.
Enterprise SLA guarantee
Contractual uptime with a named response window. Not just a status-page promise.
Role-based access control
Staff get limited access, admins full control, super-admins cross-location visibility — built in, no plugins.
Self-hosted deployment
Run the full stack on your own servers with Docker Compose. Your data never leaves your infrastructure.
Custom integrations & API
Scoped API keys for read and write access. Connect your CRM, EHR, or ticketing system directly.
Staff XMPP contacts
Register staff JIDs, resend invitations, and route internal notifications through your own XMPP environment.
Connect your phone system. Keep control.
Kelvia joins as an AI SIP endpoint through closed PBX templates. Your phone system keeps routing, extensions, PSTN carrier control, and internal transfer rules.
The AI answers over SIP and returns control to your PBX with REFER when a transfer happens.
Private VPN tunnel
Audio stays encrypted inside a dedicated point-to-point tunnel. Zero public internet exposure.
Internal extensions
Transfer to 'reception' or ext. 211 directly — no E.164 number or carrier change required.
Per-line auth
Each PBX has its own unique security key. No cross-tenant access possible.
Your infrastructure
Your PBX manages the PSTN. Kelvia plugs in as a SIP endpoint and handles the AI layer only.
No number migration
Keep your existing carrier and phone system. Kelvia adds to it, not replaces it.
SIP REFER transfers
The AI issues a SIP REFER on handoff. Your PBX routes the call internally — instantly.
Separate XMPP path
Internal XMPP can use a dedicated WireGuard route with its own host, port, and health checks.
