Dialaunch vs respond.io: the respond.io alternative for WhatsApp calls

respond.io describes itself as an AI-powered customer conversation platform for B2C sales and support. It brings WhatsApp, Instagram, Messenger, email and other channels into one inbox, with workflows, contact management and AI agents. According to its help centre, WhatsApp calls are enabled per WhatsApp channel in workspace settings, arrive in the respond.io Inbox and its mobile app, and require a minimum balance of $10 to receive calls.

Dialaunch is for businesses whose customers pick up the phone. On a single WhatsApp phone you can take one call at a time, and the next caller hits a busy line. Dialaunch lets one WhatsApp Business number take many simultaneous calls, answered by an AI agent that sounds like a person, in HD voice with no lag, and backed by a team that can listen, whisper and take over at any moment.

respond.io places WhatsApp calls inside the conversation: agents see incoming calls in the Inbox, pick up, transfer, and get recordings and transcripts next to the chat. Its blog and help centre describe Voice AI Agents that answer inbound WhatsApp calls on the Advanced plan and transfer callers to the team. At the time of writing (October 2026), we did not find documentation for keypad menus (IVR) or hold queues with music on WhatsApp calls in respond.io; check with them if you need these.

Dialaunch is designed around that call. You build the flow in a visual editor: a keypad menu, a queue with hold music, opening hours with holidays and time zones, voicemail and fallbacks. The AI agent answers in any language your customers speak, from your own information, and does the work: 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 the call to a person when asked or when the caller is upset.

Both tools take WhatsApp calls. They differ in how deep they go on voice versus chat.

• Primary focus: respond.io, omnichannel messaging with calls in the Inbox. Dialaunch, WhatsApp voice calls, with a shared inbox for WhatsApp, Instagram, Messenger and email messages.
• AI on calls: respond.io offers Voice AI Agents for inbound WhatsApp calls on its Advanced plan. Dialaunch includes the AI agent and AI minutes on every plan, with actions such as orders, bookings and callbacks.
• Call flows: respond.io, at the time of writing we did not find IVR or hold queue documentation for WhatsApp calls. Dialaunch, keypad menus, queues with hold music, opening hours, voicemail and fallbacks.
• Where agents answer: respond.io in its web Inbox and mobile app. Dialaunch on the agent’s own WhatsApp, a SIP desk phone or softphone, or the browser.
• Supervision: Dialaunch lets managers listen live, whisper, take over in one click and hand back to the AI.
• After the call: both keep call records. Dialaunch gives every call a summary, key moments and an outcome, plus reporting on answer rate, abandoned calls, waiting times and service level per agent, team and number.
• Phone numbers: Dialaunch also takes calls to your own number through your SIP trunk, in the same flows.

If your team mostly sells and supports through chat, needs advanced workflows across many messaging channels, and treats calls as an occasional extra inside a conversation, respond.io is a strong platform. Its contact management and automation depth for messaging is its home ground.

Dialaunch fits when calls are where the money and the stress are: busy hours, callers who should be answered instantly instead of ringing out, an AI agent that resolves the routine calls, and a team that steps in on the ones that matter. You get an AI agent for WhatsApp calls, call flows, live supervision and reporting in one place, from €69 a month.

A common setup uses two WhatsApp numbers: keep a sales or marketing number on respond.io for chats and campaigns, and connect the number customers call to Dialaunch.

Once a WhatsApp number is connected to Dialaunch, it stops working in the WhatsApp Business app on that number, and the app’s chat history does not move over. Setup takes about 15 minutes with a guided flow; Meta’s approval of the number can take 1 to 3 days.
