Adding WhatsApp and RCS to Your Contact Center: A Practical Checklist

Messaging has become a normal way for customers to reach businesses. Many people would rather send a quick message than wait on hold. WhatsApp is widely used in many countries, and RCS (Rich Communication Services) brings richer, app-like messages to the default texting app on supported phones.

Adding these channels to your contact center can make life easier for customers, but only if they are connected to the rest of your operation. This checklist walks through what to prepare, what to configure, and what to test, so WhatsApp and RCS become part of your service rather than another inbox nobody owns.

Before you start: decide the purpose

Write down why you are adding each channel. Common reasons include:

• Letting customers ask quick questions without calling
• Sending order, appointment, or delivery updates
• Reaching international customers who prefer WhatsApp
• Offering richer messages with buttons, images, or carousels on RCS

Having a clear purpose helps you decide routing, staffing, and what self-service to build.

Part 1: Accounts and approvals

WhatsApp

• ☐ Set up a WhatsApp Business account through your contact center platform or its approved provider.
• ☐ Complete Meta’s business verification steps.
• ☐ Choose the phone number you will use and confirm it is not already tied to a regular WhatsApp app.
• ☐ Set your business profile: display name, description, hours, and website.
• ☐ Prepare message templates for business-initiated messages. WhatsApp requires approved templates to start conversations outside the customer service window.

RCS

• ☐ Register your brand as an RCS business sender through your platform or provider.
• ☐ Complete brand verification and carrier approval steps.
• ☐ Prepare brand assets: logo, colors, and a short description.

Approval steps can take time, so start them early in your project plan.

Part 2: Consent and compliance

• ☐ Confirm how customers opt in to receive messages from you, and record that consent.
• ☐ Make it easy to opt out, and honor opt-outs across channels.
• ☐ Review your privacy policy so it covers messaging.
• ☐ Check rules for your industry and the countries you message, and get legal advice where needed.

Part 3: SMS fallback

RCS only works on devices and networks that support it. When it is not available, you need a fallback, usually SMS, so the customer still gets the message.

• ☐ Turn on SMS fallback for RCS messages.
• ☐ Write a plain-text version of every rich message. Buttons and carousels will not appear in SMS.
• ☐ Make sure fallback messages still include the key information and a clear next step.
• ☐ Track how often fallback is used so you understand real-world reach.

Vonage Contact Center lists RCS with SMS fallback among its supported channels. Availability depends on your edition and account settings.

Part 4: Routing and agent experience

This is where many teams go wrong. If WhatsApp messages land in a separate tool, you are back to silos.

• ☐ Route WhatsApp and RCS conversations through the same routing engine as voice, video, chat, and email.
• ☐ Decide which agents or skills groups handle messaging.
• ☐ Set limits on how many conversations an agent can handle at once.
• ☐ Make sure agents see the customer’s full history, including calls and emails, alongside the message.
• ☐ Log every conversation to your CRM record.
• ☐ Decide how to escalate from messaging to a call when needed.

If you use Salesforce, a platform that works inside Salesforce keeps all of this on one record. See how the Vonage Contact Center Salesforce integration works.

Part 5: Self-service and automation

• ☐ Identify the most common questions customers might send by message.
• ☐ Decide which can be answered by a virtual assistant and which need a person.
• ☐ Design a smooth handoff so the agent sees what the customer already said.
• ☐ Set expectations, such as typical response times, in your welcome message.

Our article on AI virtual assistants and call deflection covers how to design self-service that customers do not resent.

Part 6: Content and tone

• ☐ Write short, friendly message templates that sound like your brand.
• ☐ Prepare quick replies for common situations.
• ☐ Keep sensitive information out of messages unless you have the right safeguards.
• ☐ Review templates for clarity on a small phone screen.

Part 7: Testing

• ☐ Test on Android and iPhone, on different carriers where possible.
• ☐ Test RCS on a device that supports it and one that does not, to confirm SMS fallback.
• ☐ Test the handoff from bot to agent and from messaging to voice.
• ☐ Confirm that every test conversation appears on the right CRM record.
• ☐ Check reporting: can supervisors see messaging volume and response times next to voice?

Part 8: Launch and measure

• ☐ Start with a soft launch, such as one customer group or one use case.
• ☐ Watch response times, resolution rates, and opt-outs.
• ☐ Ask agents what is working and what is not.
• ☐ Expand once the basics are stable.

The bottom line

WhatsApp and RCS can make your contact center easier to reach, but the value comes from connecting them to everything else. Treat them as part of one omnichannel operation, plan for approvals and SMS fallback, and test the handoffs carefully.
