Zendesk Voice alternative for WhatsApp calls: Dialaunch vs Zendesk

Zendesk Voice offers IVR, group, prioritised, overflow and after-hours routing, a maximum queue size and wait time, callback requests instead of holding, and VoIP, PSTN and embedded calling. Zendesk also offers AI agents for voice that answer calls and redirect to a human agent when needed. It suits support teams that live in Zendesk tickets and take calls on phone numbers.

Dialaunch is for businesses whose customers call on WhatsApp. On one WhatsApp phone, the next caller hits a busy line. Dialaunch lets one WhatsApp Business number take many calls at once, each answered by an AI agent that sounds like a person, in HD voice with no lag.

Zendesk’s WhatsApp channel turns customer messages into conversations agents answer in the Agent Workspace. At the time of writing (October 2026), Zendesk’s help article on adding WhatsApp channels says a number connected to the WhatsApp Business API can no longer receive WhatsApp calls, and we did not find documentation for answering WhatsApp voice calls in Zendesk Voice. Check with Zendesk, as products change.

Dialaunch is built for exactly those calls. The AI agent answers in any language your customers speak, from your own information. It confirms orders, books appointments in Google Calendar, checks deliveries, creates callbacks and calls your systems through an API you connect. It says it is an AI and hands to a person when asked or when the caller is upset.

Zendesk covers the whole support desk. Dialaunch covers the WhatsApp call, start to finish.

• Primary channel: Zendesk, tickets and messaging, with Voice on phone numbers. Dialaunch, WhatsApp Business calls, with your own phone number joining through a SIP trunk.
• WhatsApp: Zendesk, a messaging channel (October 2026). Dialaunch, inbound WhatsApp voice calls, plus call-backs once the customer accepts a call permission request.
• AI voice: Zendesk AI agents for voice on phone calls. Dialaunch’s AI agent on WhatsApp calls, with a summary, key moments and an outcome for every call.
• Call flows: both offer IVR, queues and after-hours handling. Dialaunch runs keypad menus, queues with hold music, opening hours with holidays and time zones, voicemail and fallbacks on WhatsApp calls.
• Where agents answer: Zendesk Voice runs in the Agent Workspace. Dialaunch rings the agent’s own WhatsApp, a SIP phone or softphone, or the browser.
• Supervision: Dialaunch lets you listen live, whisper, take over in one click and hand the call back to the AI.
• Messages: Zendesk is a full ticketing suite. Dialaunch has a shared inbox for WhatsApp, Instagram, Messenger and email messages, not a ticketing system.

If your support runs on tickets, macros, a help centre and SLAs across email, chat and phone, Zendesk is the stronger platform. Zendesk Voice is a natural fit when customers call a phone number and you want calls logged as tickets.

Dialaunch fits when customers call your WhatsApp number and those calls go unanswered. The AI agent answers every call, day and night, and your team takes over when it matters. Recording with consent and retention rules, call history with a timeline, and reporting on answer rate, abandoned calls, waiting times and service level per agent, team and number are built in.

Keep Zendesk for tickets and phone support, and connect a WhatsApp number to Dialaunch for voice. A WhatsApp number can only be connected to one platform, so if Zendesk already uses your number for messaging, plan which tool takes it, or use a different number.

Once connected to Dialaunch, the number stops working in the WhatsApp Business app, and the app’s chat history does not move over. Plans start at €69 a month excl. VAT, and the 14-day trial includes 60 AI minutes.
