Select a use case to explore the challenge, the implementation flow, and the measurable impact. AI Customer Service Appointment Reminders Delivery Notifications Number Masking Outbound Sales Dialler Automated IVR Debt Collections Healthcare Calls **E-commerce · Retail · Telco** **AI Customer Service Agent** The Challenge Organizations running 24/7 contact center operations face high agent costs for routine, repetitive inquiries. Scaling human capacity to match call volume peaks is operationally unsustainable. Implementation An LLM-powered voice agent is connected to Arkan AI Voice Connect via SIP/TLS. The AI platform handles conversation logic while Arkan manages PSTN access, call routing, and media transport — delivering sub-200ms response latency across all interactions. Handles **70%+ of inbound calls autonomously** with response latency under 200ms — zero human agent involvement for routine queries. Call Flow 1 **Customer Dials In** Call arrives at an Arkan-hosted DID number from any PSTN endpoint globally. 2 **SBC Routes to AI Platform** Arkan's Cloud SBC routes the call over SIP/TLS to the configured AI voice agent endpoint. 3 **AI Engages the Caller** The AI platform processes speech, runs inference, and responds — all within the sub-200ms media path maintained by Arkan's edge infrastructure. 4 **Escalation if Needed** If the call requires human handling, Arkan bridges to the live agent platform (Teams, Genesys, Zoom) with zero disruption to the call session. 5 **CDR Logged** Only call detail records are retained. No audio content or conversation data stored on Arkan infrastructure. **Healthcare · Banking · Government · Legal · Auto** **Automated Appointment Reminders & Confirmations** The Challenge Manual appointment confirmation calls consume significant agent time. No-show rates remain high when reminders rely solely on SMS or email, particularly in regulated industries where spoken confirmation is required. Implementation CRM sends an API request to Arkan 24 hours before the appointment. Arkan initiates the outbound call, TTS speaks appointment details, captures the patient's DTMF keypad response, and fires the result back to the CRM via webhook — all without agent involvement. Reduce no-shows by up to **40%**. Zero agent time required per confirmation cycle. Automated Confirmation Flow 1 **CRM Sends API Request** Business system triggers Arkan API 24h before appointment with patient number and appointment data. 2 **Arkan Places the Call** Arkan's voice engine dials the patient via carrier PSTN automatically. 3 **TTS Reads Details** Appointment date, time, and location spoken via real-time TTS. Caller is asked to confirm or reschedule. 4 **DTMF Keypad Response** Customer responds by pressing 1 (confirm) or 2 (reschedule). Arkan captures the input precisely. 5 **Result Sent to CRM** Webhook fires instantly with confirmation status. CRM updates record, calendar adjusts automatically. **E-commerce · Logistics · Retail · Pharma · Food Delivery** **Shipment & Delivery Notifications** The Challenge Failed deliveries are costly — returned parcels, re-routing fees, and increased customer service volume. SMS-based notifications are frequently missed, particularly in markets with lower smartphone penetration. Implementation When an OMS detects a shipment status change, it sends an API request to Arkan with order details. Arkan places an outbound call, speaks the delivery details via TTS, captures the customer's confirmation, and returns the result — updating the delivery route in real time. Cut failed deliveries significantly, reduce inbound service calls, and improve NPS — **without a single agent touchpoint**. Delivery Notification Flow 1 **OMS Detects Status Change** Shipment dispatched or out-for-delivery event triggers an API call to Arkan with order and customer data. 2 **Arkan Calls the Customer** Outbound call placed immediately via PSTN to the customer's registered number. 3 **TTS Delivers Notification** "Your order #12345 is out for delivery. Press 1 to confirm your address or 2 to reschedule." 4 **Customer Input Captured** Arkan captures DTMF or voice response and sends result back to the OMS via webhook instantly. 5 **Route Updated in Real Time** Driver notification updated automatically. No human dispatcher involvement required. **Ride-Hailing · Delivery · Marketplaces · Healthcare · Legal** **Number Masking & Private Calls** The Challenge Platforms connecting two parties — drivers and riders, service providers and clients — face compliance and privacy risks when real phone numbers are exposed. Data protection regulations in MENA and globally increasingly require number masking in two-party communications. Implementation The application requests a masked call session via API. Arkan assigns a temporary virtual number. Both parties dial the virtual number and connect through Arkan's SBC without either side seeing the other's real number. On session end, the virtual number is released. Full privacy protection, zero number exposure, and real-time connections — **PDPL and GDPR aligned**. Number Masking Flow 1 **App Requests Masked Session** Application sends API request to Arkan specifying the two parties requiring connection. 2 **Arkan Assigns Virtual Number** A temporary DID is provisioned and both parties receive the same virtual number to call. 3 **Both Parties Connect** Each caller dials the virtual number. Arkan's SBC bridges both calls — neither party sees the other's real number at any point. 4 **Session Ends** When the call concludes, the virtual number is released back to the pool. CDR sent to the platform. No recording stored by Arkan. **SaaS · Financial Services · Real Estate · Telecoms** **AI Outbound Sales Dialler** The Challenge Scaling outbound sales call campaigns traditionally requires proportional growth in agent headcount. Per-minute carrier costs compound rapidly as call volume increases, making large-scale outbound campaigns economically challenging. Implementation An AI voice agent is connected to Arkan AI Voice Connect. The dialler system triggers outbound calls via API, the AI agent handles the initial conversation, qualifies the prospect, and transfers hot leads to live agents — all via the same Arkan infrastructure with no re-routing latency. Scaled from **50 to 2,000 concurrent calls in 3 weeks** using Arkan's channel bundle infrastructure. AI Outbound Dialler Flow 1 **CRM Triggers Dial Campaign** Batch API calls sent to Arkan with lead list and call parameters. 2 **Arkan Places Concurrent Calls** Multiple outbound calls initiated simultaneously via PSTN across available channels. 3 **AI Qualifies the Prospect** AI voice agent handles opening conversation, captures intent, and qualifies based on configured criteria. 4 **Live Transfer or Voicemail** Qualified leads transferred instantly to human agents. Others receive a personalized TTS message with callback options. 5 **Outcome Logged to CRM** Call outcome, disposition, and any recording are pushed to the CRM via webhook in real time. **Government · Banking · Utilities · Telco · Insurance** **Multi-Step Automated IVR** The Challenge Traditional static IVR trees are inflexible and costly to maintain. They cannot adapt to real-time data, resulting in poor caller experience and high fallthrough rates to live agents for queries that could be resolved automatically. Implementation Arkan's inbound call webhooks query the business system dynamically on each call. The IVR logic is driven by live data—account status, open tickets, eligibility—not static decision trees. Complex branching is executed through webhook responses without any re-engineering of the call flow. Complex branching driven by business rules — **no static trees**. Dynamic IVR responding to live system state. Dynamic IVR Flow 1 **Caller Dials In** Customer calls the Arkan-hosted number from any device, any country. 2 **Webhook Fires to Business System** Arkan sends caller's number and call context to the CRM or application backend. 3 **System Returns IVR Instructions** Application responds with dynamic IVR instructions — which message to play, what input to capture, how to branch — based on live data. 4 **Arkan Executes on Live Call** Instructions executed within milliseconds: play audio, speak TTS, capture input, connect to agent, or end the call. 5 **Result Logged** All call events, captured inputs, and disposition sent back to the system in structured JSON via webhook. **Banking · Financial Services · Utilities · Leasing** **Automated Debt Collections & Payment Reminders** The Challenge Collections calling requires high-volume, structured outreach with compliance-sensitive scripting. Manual agent calls at scale are expensive, and non-compliant conversations create regulatory exposure in MENA markets governed by SAMA and CITC frameworks. Implementation The collections system triggers Arkan API calls at scheduled intervals. TTS delivers compliance-approved payment reminder scripts with DTMF options for payment confirmation or callback scheduling. All call records and outcomes are delivered back to the collections platform in real time. Compliance-approved scripts delivered at scale — **no agent involvement** for standard payment reminders. Escalation available for complex cases. Collections Call Flow 1 **Collections System Sends Batch** API request submitted with account numbers, outstanding amounts, and script parameters for each call. 2 **Arkan Places Scheduled Calls** Outbound calls placed according to contact strategy rules — times, retries, channel limits. 3 **TTS Delivers Reminder** Compliance-approved script spoken dynamically with customer name, amount, and due date from system data. 4 **Customer Responds or Defers** Press 1 to confirm payment. Press 2 for callback scheduling. Press 3 to connect to agent. 5 **Outcome Synced** CDR and DTMF results delivered via webhook. Account status updated automatically in the collections platform. **Hospitals · Clinics · Pharmacies · Mental Health** **Healthcare Patient Communication Automation** The Challenge Healthcare providers manage complex, high-volume patient communication requirements — appointment reminders, prescription pickups, lab result notifications, and discharge follow-ups — all with strict data privacy obligations under Saudi NDMO and HIPAA-equivalent frameworks. Implementation The HIS or EMR system triggers Arkan API calls for each patient communication event. TTS delivers personalized notifications. Privacy-by-design architecture ensures no patient conversation data is retained on Arkan infrastructure — only metadata CDRs are logged. Handles **10,000+ monthly patient interactions** with HIPAA-aligned call routing and zero PHI stored on voice infrastructure. Healthcare Communication Flow 1 **HIS Triggers Communication Event** EMR/HIS identifies patient communication needs (appointment, lab result, prescription) and sends an API request. 2 **Personalised Call Initiated** Arkan places a call to the patient. TTS delivers personalized messages using the patient's name and appointment or test details. 3 **Patient Responds** DTMF options for confirmation, rescheduling, or connection to clinical staff. Call flow adapts to patient input in real time. 4 **Result Returned to HIS** Patient confirmation or action status is sent back to EMR via webhook within seconds. 5 **Privacy Preserved** Only CDR metadata is retained. No patient voice data or health information stored on Arkan infrastructure at any point. ## **Product Comparison** ## **Choosing the Right *Product*** Both products run on the same Arkan SBC infrastructure.
