Why teams look for a Callbell alternative
You also need email and SMS in the same inbox, and Callbell does not list them as channels.
You want an AI agent to answer phone and WhatsApp calls, not only text chats.
You prefer AI usage covered by monthly credits included in your plan, rather than a separate wallet you top up.
What Rexenda does differently
Voice AI agents that answer and place phone and WhatsApp calls, use tools during the call and save the transcript and summary to the CRM.
Email, SMS, Instagram, Messenger, Telegram and web chat in the same inbox as WhatsApp, with one contact identity across channels.
A CRM included, with AI lead scoring, pipeline and quotes. Rexenda does not charge for WhatsApp messages: Meta bills them to your own WhatsApp Business account.
How to switch
Bring your contacts in a CSV file: Rexenda lets you map the columns, review before confirming and undo an import if needed. WhatsApp connects in minutes through Meta's official signup flow; if your number runs on the WhatsApp Business app, coexistence lets you keep using the app. A number already connected to another platform's API must be released there first.
When Callbell may still be the right choice
Staying with Callbell may make sense if your team works mainly in messaging apps such as Telegram and TikTok, does not need email, SMS or phone calls, and is comfortable with per-user pricing and an AI wallet paid by the message.
Questions
Is Rexenda a good alternative to Callbell?
Yes, if you need more than messaging apps. Rexenda brings WhatsApp, Instagram, Messenger, Telegram, web chat, email, SMS and phone calls into one inbox. Its AI agents can book meetings, update the CRM and send quotes, and they can also answer calls. If your team only needs a shared inbox for chat apps, Callbell may be enough.
How is AI billed in Rexenda compared with Callbell?
In Rexenda, every plan includes monthly AI credits, and one AI reply uses one credit; extra credit packs are available. Voice minutes and attachment reading draw from the same balance. Callbell's AI agent draws from a prepaid wallet that you top up, with a cost per message that depends on how the agent is configured.
Can I keep my WhatsApp number when switching from Callbell?
In most cases, yes. Rexenda connects WhatsApp through Meta's official signup flow in a few minutes. A number that is currently connected to Callbell's API has to be released there before you connect it to Rexenda. If the number runs on the WhatsApp Business app, coexistence lets you keep using the app alongside Rexenda.
