Voice AI agents that answer and place calls on Rexenda phone numbers and on WhatsApp, speak natural Spanish and English and let callers interrupt. Outbound campaigns follow calling windows, retries, a do-not-call list, quiet hours and daily caps per contact.
A Bland AI alternative with voice, WhatsApp and CRM in one app
Bland AI is an enterprise voice AI platform for building, running and monitoring AI phone agents at scale, with per-minute pricing, APIs and options to run on dedicated infrastructure. Rexenda is a business application where AI agents answer and place phone and WhatsApp calls, reply on WhatsApp and work inside a built-in CRM, calendar and quotes.

Why teams look for a Bland AI alternative
Plan limits. According to Bland's pricing page, its Start plan has no platform fee but charges $0.14 per minute and caps usage at 100 calls a day and 10 concurrent calls, while the Build plan raises the limits for a $299 monthly platform fee.
Enterprise focus. Bland's site is aimed at security-conscious enterprises in regulated industries, offers forward-deployed engineers and says most production agents go live in two to six weeks, a pace built for large projects.
WhatsApp. Bland's API documentation marks WhatsApp and iMessage messaging as Enterprise only, so smaller teams that sell and serve customers on WhatsApp need another tool for that channel.
What Rexenda does differently
WhatsApp messaging does not require an enterprise contract: connect your number through the official API with Meta's Embedded Signup and handle it next to Instagram, Messenger, web chat, email and SMS in one inbox. Meta bills message fees directly to your own account.
When a call ends in a sale, the agent can send a quote with an acceptance link and a card payment link paid into your own Stripe account, check whether the payment arrived and, in Mexico, issue a CFDI e-invoice.
The agent works inside Rexenda's own CRM and calendar: during the call it checks availability, books meetings, saves the caller's details and updates the pipeline, and the transcript and summary stay with the contact. No code or engineering project is required.
How to switch
Take your call scripts and knowledge content from Bland and use them to set up the agent in Rexenda, from a template or by describing its job. Get a number in the app or request a port of your current one where the carrier allows it (some countries require identity documents), connect WhatsApp with Meta's Embedded Signup and import contacts from a CSV file. Make a test call: the agent goes live only after one succeeds.
When Bland AI may still be the right choice
Bland may be the better choice if you need agents running on dedicated infrastructure, on-premises or in your own private cloud, need the certifications Bland lists such as HIPAA and FedRAMP, want to keep your existing Twilio account or SIP trunks, or place very high call volumes from your own code through an API. Rexenda has no public API with keys today, only outgoing webhooks.
Questions
How is Rexenda different from Bland AI?
Bland focuses on enterprise voice automation at scale, with APIs, dedicated infrastructure and per-minute plans. Rexenda is a business application with a free plan forever, where the same AI agents handle phone calls, WhatsApp calls and WhatsApp messages and work inside a built-in CRM with calendar, quotes and payment links.
Does Rexenda have an API like Bland?
Not a public one. Rexenda has no public REST API with keys today; it sends outgoing webhooks, and AI agents can call external APIs that you set up as actions. If your product needs to start calls from your own code, a developer platform like Bland may fit better.
How are AI voice calls billed in Rexenda?
Voice minutes are paid from the AI credits in your plan: one minute of AI voice call uses 12 credits, and you can buy extra packs. Phone numbers have a separate monthly charge, and some countries require identity documents before a number is assigned. The agent never hangs up on a caller mid-conversation; it only ends a call after a long silence or if your workspace runs out of credit.
