AI Customer Service Agent
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.
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.
Customer Dials In
Call arrives at an Arkan-hosted DID number from any PSTN endpoint globally.
SBC Routes to AI Platform
Arkan's Cloud SBC routes the call over SIP/TLS to the configured AI voice agent endpoint.
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.
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.
CDR Logged
Only call detail records are retained. No audio content or conversation data stored on Arkan infrastructure.

Automated Appointment Reminders & Confirmations
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.
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.
CRM Sends API Request
Business system triggers Arkan API 24h before appointment with patient number and appointment data.
Arkan Places the Call
Arkan's voice engine dials the patient via carrier PSTN automatically.
TTS Reads Details
Appointment date, time, and location spoken via real-time TTS. Caller is asked to confirm or reschedule.
DTMF Keypad Response
Customer responds by pressing 1 (confirm) or 2 (reschedule). Arkan captures the input precisely.
Result Sent to CRM
Webhook fires instantly with confirmation status. CRM updates record, calendar adjusts automatically.

Shipment & Delivery Notifications
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.
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.
OMS Detects Status Change
Shipment dispatched or out-for-delivery event triggers an API call to Arkan with order and customer data.
Arkan Calls the Customer
Outbound call placed immediately via PSTN to the customer's registered number.
TTS Delivers Notification
"Your order #12345 is out for delivery. Press 1 to confirm your address or 2 to reschedule."
Customer Input Captured
Arkan captures DTMF or voice response and sends result back to the OMS via webhook instantly.
Route Updated in Real Time
Driver notification updated automatically. No human dispatcher involvement required.

Number Masking & Private Calls
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.
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.
App Requests Masked Session
Application sends API request to Arkan specifying the two parties requiring connection.
Arkan Assigns Virtual Number
A temporary DID is provisioned and both parties receive the same virtual number to call.
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.
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.

AI Outbound Sales Dialler
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.
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.
CRM Triggers Dial Campaign
Batch API calls sent to Arkan with lead list and call parameters.
Arkan Places Concurrent Calls
Multiple outbound calls initiated simultaneously via PSTN across available channels.
AI Qualifies the Prospect
AI voice agent handles opening conversation, captures intent, and qualifies based on configured criteria.
Live Transfer or Voicemail
Qualified leads transferred instantly to human agents. Others receive a personalized TTS message with callback options.
Outcome Logged to CRM
Call outcome, disposition, and any recording are pushed to the CRM via webhook in real time.

Multi-Step Automated IVR
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.
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.
Caller Dials In
Customer calls the Arkan-hosted number from any device, any country.
Webhook Fires to Business System
Arkan sends caller's number and call context to the CRM or application backend.
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.
Arkan Executes on Live Call
Instructions executed within milliseconds: play audio, speak TTS, capture input, connect to agent, or end the call.
Result Logged
All call events, captured inputs, and disposition sent back to the system in structured JSON via webhook.

Automated Debt Collections & Payment Reminders
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.
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 System Sends Batch
API request submitted with account numbers, outstanding amounts, and script parameters for each call.
Arkan Places Scheduled Calls
Outbound calls placed according to contact strategy rules — times, retries, channel limits.
TTS Delivers Reminder
