Built for your stack

From Salesforce lead routing to custom Node.js backends — one API, infinite workflows.

CRM integrations

Push call outcomes, transcripts, and disposition codes to Salesforce, HubSpot, Zoho, and Pipedrive. Map custom fields and trigger follow-up tasks automatically when a call completes.

Includes: Lead sync, activity logging, custom object mapping

SIP & telephony

Production SIP connectivity included on every plan. Provision local and toll-free numbers, manage call routing, and leverage carrier-grade voice quality without managing your own trunk infrastructure.

Includes: Number provisioning, SIP trunks, CNAM lookup

SMS messaging (add-on)

Two-way SMS on your business numbers for confirmations, reminders, and post-call follow-ups. Optional add-on — not bundled with voice plan minutes.

Includes: Outbound/inbound SMS, API + webhooks when enabled

Real-time media

Low-latency audio streaming over WebRTC. Enables natural turn-taking, barge-in, and multi-party scenarios for advanced agent workflows.

Includes: Real-time audio, agent rooms, media recording

Webhooks

Receive signed POST payloads on call.started, call.ended, transcript.ready, and agent.handoff events. Verify signatures with your webhook secret and retry logic built in.

Includes: HMAC signatures, retry with backoff, event filtering

REST API

The core of VOXBRIDGE. Authenticate with Bearer tokens, queue outbound calls, configure inbound routes, manage agents, and retrieve call logs — all via JSON over HTTPS.

POST /v1/calls/outbound Authorization: Bearer sk_live_... Content-Type: application/json { "to": "+15551234567", "agent_id": "agent_welcome_v2", "context": { "client_name": "Jane", "reference_number": "398690" } }

CRM & workflow integrations

Connect VOXBRIDGE to the CRMs and automation tools your team already uses — sync leads, log call outcomes, and trigger follow-ups without custom middleware.

Use webhooks and REST to push call transcripts, disposition codes, and lead updates into your CRM — or route inbound callers using live CRM lookups.

Popular integration patterns

Teams ship these workflows first — then expand into custom backends and multi-channel automation.

  • Outbound welcome calls — Trigger a personalized AI call when a lead submits a form via your CRM webhook.
  • Inbound support routing — Route callers to the right AI agent based on IVR selection and CRM lookup.
  • Post-call automation — Send transcript summaries to Slack, update deal stages, or create support tickets.
  • Custom backends — Use any language or framework; our REST API is stateless and idempotent.
