Retell AI alternative for agencies
Keep client voice agents portable and reviewable
Retell runs the voice agent. VoiceForge is the agency control plane around it — a validated, versioned Agent Spec, isolated workspaces and a hard compliance gate so virtual receptionist delivery stays repeatable.
Separate behavior from the provider
Define goals, call flow, tools, guardrails and compliance once. The runtime adapter translates the spec for OpenAI Realtime or the in-house Azure pipeline without rewriting the operating model.
Review and test a known version
Generate the spec from a brief, inspect it, run a browser test call and publish a version that can be paused and audited. No silent dashboard edits.
Operate multiple clients safely
Workspaces scope agents, knowledge, calls and analytics per client. One clinic never sees another clinic’s transcripts or bookings.
Monitor business outcomes
Inspect transcripts, outcomes, transfer behavior, tool success, fallbacks and cost per successful outcome — not just minutes — so answering service ROI is provable.
When Retell is still the right call
Use Retell directly when a single-team deployment with provider-native tuning is the whole job. Use VoiceForge when the repeated cost is governance, handoff and multi-client margin.
Frequently asked questions
- How is VoiceForge different from Retell AI?
- Retell configures individual voice agents on its platform. VoiceForge treats the agent as a versioned, schema-validated Agent Spec that is reviewed and tested before telephony, then wrapped in the agency layer: isolated client workspaces, white-label branding, per-client analytics and a compliance gate on every outbound call.
- Does VoiceForge support virtual receptionist use cases like Retell?
- Yes. Virtual receptionist, AI receptionist and answering service templates are built in — inbound answering, call routing, message taking and appointment booking scoped per client workspace so one client never sees another client’s data.
- Can my clients see their own agents and calls?
- Yes. Each client gets an isolated workspace under your branding with scoped agents, knowledge, calls and analytics. Client roles and shareable demo links make handoff clean without dashboard sprawl.
- What happens when a client asks for a change?
- Changes produce a new version of the Agent Spec. Inspect the diff, run a browser test call against the new version and publish deliberately — the history stays auditable instead of living in whoever edited the dashboard last.
- What does VoiceForge cost vs Retell?
- Retell is usage-based per minute. VoiceForge is flat $99/$299/$999 per month covering spec generation, test calls, workspaces and analytics; telephony is transparent and provider-neutral so agencies keep predictable margin.
