For a Customer Service team, that means WhatsApp Call is no longer just an "extra channel" — it needs to be treated on par with a PSTN call: routed into the right queue, logged properly, and measurable. This article covers how to route incoming WhatsApp calls into a Customer Service workflow in 3CX, once WhatsApp SIP Calling integration is already active. **Haven't enabled WhatsApp Calling in 3CX yet?** Follow the guide [How to Enable WhatsApp Voice Calling (WhatsApp SIP Calling) in 3CX](https://solusipbx.com/pusat-bantuan/cara-mengaktifkan-panggilan-suara-whatsapp-whatsapp-sip-calling-di-3cx/) (Indonesian) first before continuing with this article. ## **Why WhatsApp Call Matters for Customer Service** - **One tap from chat to voice.** A customer already chatting on WhatsApp Business can tap the *Call* button directly, without leaving the app or dialing a separate phone number. - **No airtime or long-distance charges.** Calls run over mobile data, so customers feel more comfortable reaching your CS team any time. - **Stays in the same ecosystem as other calls.** Since it arrives as a SIP trunk into 3CX, a WhatsApp call can follow the exact same workflow as a PSTN call — routed into a Queue, recorded, reported, and monitored on a Wallboard. - **Less overhead for agents on the WhatsApp Business App.** Agents don't need to manually log into the WhatsApp Business app; the call simply shows up in the 3CX Webclient, Desktop App, or IP Phone like any other inbound call. ## **Prerequisites** Before setting up the Customer Service flow, make sure: - The WhatsApp SIP Trunk has already been **successfully created and is active** in the 3CX Admin Console. - You already have a dedicated Customer Service **Call Queue** or **Ring Group** (if not, create one first under Admin Console → Queues). - The agents who will take these calls already have an **active extension** and are logged into one of the clients (Webclient, Desktop App, Mobile App, or IP Phone). ### **Step 1: Point the WhatsApp Trunk's Default Route to the CS Queue** 1. Open Admin Console → SIP Trunks, and select the WhatsApp trunk you already created. 2. Under **Inbound Rules / Default Route**, change the destination from a single extension to the **Customer Service Call Queue**. 3. Save the configuration. This makes every incoming WhatsApp call automatically follow the queue's distribution logic (round robin, ring all, or skill-based), instead of going to just one person. ### **Step 2: Add an IVR Before the Queue (Optional but Recommended)** If your CS team handles more than one type of service (e.g. Sales, Support, Billing), route the WhatsApp trunk to a **Digital Receptionist (IVR)** first, then forward it to the appropriate queue. **Example of a simple IVR menu:** - Press 1 for Customer Service - Press 2 for Sales - Press 3 for Billing This IVR can also be pointed to an **AI Agent** to automatically answer common questions before handing off to a human agent, so the queue doesn't pile up during busy hours. > **Also read:**[How to Enable WhatsApp Voice Calling (WhatsApp SIP Calling) in 3CX](https://solusipbx.com/pusat-bantuan/cara-mengaktifkan-panggilan-suara-whatsapp-whatsapp-sip-calling-di-3cx/) (Indonesian) ### **Step 3: Decide How Agents Will Answer Calls** Agents don't need a separate WhatsApp Business app. Once a WhatsApp call lands in the queue, it can be answered through: | **Client** | **Best For** | | --- | --- | | 3CX Webclient | Remote/WFH agents, no install needed | | 3CX Desktop App | Office agents with a headset | | 3CX Mobile App | Agents who are frequently mobile | | IP Phone | A physical CS/help desk | Make sure agent presence status (**Available / Away / DND**) is set correctly so WhatsApp calls don't end up going to an agent who isn't ready to take them. ### **Step 4: Enable Call Recording & Monitoring** Since a WhatsApp call arrives as a regular SIP call, all of the following native 3CX features automatically apply: - **Call Recording** — for quality assurance and resolving complaints. - **Live Monitoring / Call Barge-Listen-Whisper** — supervisors can monitor calls in real time. - **Call Reporting** — duration, number of answered/missed calls, and per-agent performance are logged automatically. Turn it on via Admin Console → Queues → [CS Queue] → Recording if it isn't already enabled by default. ### **Step 5: Monitor Performance via Wallboard or Grafana** For CS teams with a high volume of WhatsApp calls, use the **3CX Wallboard** or a **Grafana Dashboard** to keep track of: - Number of incoming WhatsApp calls per hour (to identify peak hours) - Average Wait Time in the queue - Missed calls that need to be followed up ## **Best Practices for a Customer Service Team** - **Combine it with an AI Agent** to answer repetitive questions (business hours, order status) before the call reaches an agent. - **Keep the queue separate** if WhatsApp Call volume is high enough, so it doesn't mix with your PSTN queue and performance can be measured per channel. - **Follow up on missed calls** from 3CX reports — customers whose calls went unanswered tend not to call back, so proactively reaching out matters for customer satisfaction. - **Review recordings periodically** as material for agent coaching. ## **Frequently Asked Questions** - **Does the customer need to install anything extra to call over WhatsApp?** No. The customer just taps the *Call* button in a WhatsApp Business chat as usual. - **Does the agent have to open the WhatsApp Business app to answer?** No. The call is answered directly through the 3CX Webclient, Desktop App, Mobile App, or IP Phone — just like answering a regular phone call. - **Can WhatsApp calls land in the same queue as regular phone calls?** Yes, but it's recommended to keep them separate if volume is high, so per-channel performance reports stay accurate. - **Can WhatsApp calls be recorded like regular calls?** Yes. Since it comes in as a SIP trunk, all of 3CX's native recording, monitoring, and reporting features automatically apply. - **Can you make outbound calls to a customer over WhatsApp?** Not currently. The current implementation of WhatsApp SIP Calling in 3CX only supports inbound calls. Outbound calls from 3CX to WhatsApp are not yet supported. > **Also read:** [WhatsApp Business Calling API with 3CX PBX](https://solusipbx.com/whatsapp-business-calling-api-dengan-pbx/) (Indonesian)
