CallSphere integrates with HubSpot, Salesforce, Zendesk, Freshdesk, Shopify, WooCommerce, Stripe, Square, Twilio, and more. Custom integrations are available on Growth and Scale plans.

Our AI agents scale automatically to handle unlimited concurrent calls and chats. There are no wait times or busy signals—every customer gets an immediate response, even during peak hours.

Yes. Voice and chat agents can securely collect payment information and process transactions through Stripe or Square during the conversation, with PCI-DSS compliant handling.

CallSphere includes intelligent escalation. If the AI detects a complex issue or the customer requests a human, the call or chat is seamlessly transferred to your team with full context and conversation history.

Every plan includes a real-time analytics dashboard with metrics like resolution rate, sentiment analysis, call duration, topic modeling, and CSAT scores. Export reports in CSV or connect to your BI tools.

Yes. You can export call logs, transcripts, analytics, and customer data at any time via the dashboard or API. We support CSV, JSON, and direct database integrations. Your data is always yours.

CallSphere is designed for businesses of all sizes. The Starter plan at $149/mo includes 1 AI voice agent, 1 chat agent, and 2,000 interactions — ideal for small businesses that want 24/7 phone coverage without hiring a receptionist. Setup takes as little as 24 hours.

CallSphere AI receptionist plans start at $149/mo (Starter), $499/mo (Growth with 3 agents and 10,000 interactions), and $1,499/mo (Scale with unlimited agents and 50,000 interactions). Annual billing saves 20%. Every plan includes a free 30-day pilot with no credit card required.

Yes. CallSphere offers HIPAA-compliant AI voice agents that handle appointment scheduling, rescheduling, and cancellations for medical offices. Agents integrate with Google Calendar, Calendly, and custom EHR systems, and can collect patient intake information during the call.

Traditional IVR systems use rigid menu trees ('Press 1 for sales'). CallSphere AI voice agents have natural conversations — callers speak normally and the agent understands intent, asks follow-up questions, and completes tasks like booking appointments or processing payments, all without menu prompts.

Most CallSphere customers are live within 3-5 business days. Simple use cases like appointment scheduling or FAQ handling can be running in 24 hours. Complex deployments with custom integrations, knowledge bases, and multi-agent workflows typically take 1-2 weeks with dedicated onboarding support.

Yes. CallSphere works with your existing phone number through call forwarding or SIP trunking. You can also port your number directly or use a new number provisioned through Twilio. Your callers experience no change — they dial the same number they always have.

Growth and Scale plans include a 99.9% uptime SLA. Scale customers receive a dedicated SLA document with penalties and remedies. Starter plans target 99.5% uptime without a contractual guarantee.

Yes. We provide a GDPR-compliant DPA on request for all paid plans. The DPA covers data processing scope, sub-processor lists, breach notification timelines, and data subject rights.

CallSphere infrastructure runs on AWS US-East by default. Scale customers can request data residency in the EU (Frankfurt) or Asia-Pacific (Singapore). Contact sales for region-specific deployments.

Each agent has an explicit tool allowlist defined in the system prompt. Tools like payment processing or appointment booking must be individually enabled. Agents cannot invoke tools that are not on their allowlist.

SSO via SAML 2.0 and OpenID Connect is available on Scale plans. Growth plans support Google Workspace SSO. Starter plans use email/password authentication with optional two-factor authentication.

Yes. All agent actions, tool invocations, escalations, and admin changes are recorded in an immutable audit log. Logs are retained for 12 months and can be exported via API or dashboard.

CallSphere is model-agnostic and supports leading LLMs from OpenAI, Anthropic, and Google. The model is selected per agent based on task complexity, latency requirements, and cost. Scale customers can specify a preferred provider.

End-to-end voice latency is under 1.5 seconds for most turns. This includes ASR transcription (~300ms), LLM reasoning (~500ms), and TTS synthesis (~200ms). Network and telephony add ~200-400ms depending on carrier.

The architecture has 6 layers: Transport (WebRTC, SIP, WebSocket), Speech (ASR/TTS), Reasoning (LLM with system prompt), Actions (tool calling, API execution), Safety (guardrails, PII redaction), and Integrations (CRM, calendar, payments).

Yes. Define a tool with a name, description, and JSON schema for parameters. CallSphere calls your API endpoint when the agent invokes the tool. Authentication supports API keys, OAuth 2.0, and webhook signatures.

Each conversation maintains a turn-by-turn state object that includes extracted entities, tool results, and context. State persists for the duration of the call or chat session. Cross-session memory is available on Growth and Scale plans.

CallSphere runs across multiple availability zones. If one zone fails, traffic routes to a healthy zone within 30 seconds. During a full outage, calls forward to your configured fallback number. Chat displays a maintenance message with estimated recovery time.

Yes. Chat agents can be deployed on SMS (via Twilio or Vonage). The same agent logic, tools, and knowledge base apply across all channels.

Yes. Connect your existing Twilio account by providing your Account SID and Auth Token. CallSphere provisions phone numbers and routes calls through your account. You retain full control of your Twilio billing.

Yes. Configure webhooks for events like call started, call ended, escalation triggered, appointment booked, and payment processed. Payloads are signed with HMAC-SHA256 for verification.

Yes. Upload PDFs, DOCX files, or plain text to create a knowledge base. CallSphere uses retrieval-augmented generation (RAG) to ground agent responses in your documentation. Knowledge bases refresh within 5 minutes of upload.

Yes. Outbound campaigns can be configured via API or dashboard. Use cases include appointment reminders, payment follow-ups, and survey calls. Outbound calls follow TCPA compliance rules and respect do-not-call lists.

Agents are grounded in structured tools and knowledge bases. When the agent cannot find a factual answer, it says so rather than guessing. System prompts include explicit instructions to avoid fabrication. RAG retrieval provides source attribution.

Yes. Define topics the agent must refuse to discuss (e.g., competitor pricing, legal advice, medical diagnoses). Denied topics trigger a polite decline response and optionally escalate to a human.

Handoff triggers include: customer explicitly requests a human, agent confidence falls below a threshold, conversation exceeds a turn limit, sensitive topics are detected, or a tool execution fails repeatedly. All triggers are configurable per agent.

Yes. PII redaction is enabled by default for call transcripts and logs. Credit card numbers, SSNs, and health identifiers are masked before storage. Unredacted transcripts are available only to authorized admin roles on Scale plans.

Yes — we offer a free 30-day pilot with full feature access. No credit card is required to start. At the end of the pilot, choose a plan or your account pauses automatically.

Yes. Upgrade or downgrade between Starter ($149/mo), Growth ($499/mo), and Scale ($1,499/mo) at any time. Changes take effect at the next billing cycle. Prorated credits apply when upgrading mid-cycle.

Onboarding includes a kickoff call, system prompt configuration, tool setup, knowledge base upload, testing, and go-live support. Starter onboarding is self-serve with documentation. Growth and Scale include a dedicated onboarding specialist.

Yes. Annual billing is available at a 20% discount. Starter: $119/mo billed annually. Growth: $399/mo billed annually. Scale: $1,199/mo billed annually. Contact sales for multi-year agreements.
