Executive summary
Secretaría.es is one of Spain's most used phone-secretary services. Honest comparison with IACall: 24/7 coverage, simultaneous calls, CRM integration, languages and real cost ranges (the 500-700 €/month case).
Secretaría.es is one of Spain's best-known outsourced phone-secretary services. A human picks up on your behalf, introduces your firm and forwards the message. It works. But more and more firms now combine it with, or replace it by, AI voice agents. Here is an honest comparison between Secretaría.es and IACall.

- Pricing: monthly fee + minute bundle, with overage charges.

Head-to-head
| Criterion | Secretaría.es | IACall |
|---|---|---|
| Service model | Outsourced human team answering on your behalf | Dedicated AI voice agents for your firm |
| Response time | 2-4 rings during hours, voicemail off-hours | Under 1 second, 24/7 |
| Coverage | Mon-Fri working hours, holidays per plan | 24/7/365, no surcharge |
| Concurrency | Capped by staff on shift | High concurrency: peaks answered without queue |
| Average call length | Longer: intro, manual note-taking, transcription | Shorter and more efficient: agent qualifies straight to the point |
| Languages | Spanish, English on higher plans | Iberian, LATAM, English & 30+ languages |
| Integrations | Email, web form or Zapier | FincasPlus and ADComunidad in production; the rest case by case via API |
| Calendar | Confirms appointment, forwards by email | Writes directly to Google Calendar / Outlook |
| Qualification | Fixed script shared across customers | Per-firm, per-department decision tree |
| Recording & traceability | No standard native recording; notes typed by the agent | Recording + transcription of every call and full analytics platform |
| Notifications | Email/SMS/app, paced by the operator | Instant email and WhatsApp, routed by department |
| Human transfer | Cold transfer | Warm transfer with full case context |
| Pricing model | Monthly fee + call/minute bundle, overage charges | Closed minute package, no surprises |
| Cost at same volume | Mid-sized firms reach 500-700 €/month with extras | A small fraction of that |
Control and traceability: the biggest difference
With a human outsourced service you get the note the operator typed — no audio, no transcript, no aggregate metrics. With IACall, every call is recorded and transcribed, available in the analytics platform, with notifications hitting email and WhatsApp instantly.
Shorter, more efficient calls
A human secretary needs to introduce, take notes by hand and read back. An AI voice agent qualifies straight to the point, writes to the CRM while speaking and books in the same step. Result: shorter calls and fewer minutes consumed at equal volume.
The 500-700 €/month story
Mid-sized firms coming from Secretaría.es typically end up around 500-700 €/month once overage kicks in — and still miss calls. Moving the first layer to IACall usually costs a small fraction of that.
On AI disclosure
IACall lets you configure when the caller is told it's an AI — first sentence, after qualification, or only on request. Either way, being answered instantly is always better than ringing through or voicemail.
When Secretaría.es still makes sense
- Very small firms with low volume and exclusively VIP clientele.
- Mostly emotional, non-repetitive calls.
- Teams with no CRM and no plan to adopt one.
When to move to IACall
- Monthly bill near or above 500 €.
- Calls lost at peak times or out of hours.
- You want notes and audio in your CRM, not in an email.
- Multi-language or multi-region clientele.
- You need real analytics on call volume and outcomes.
The hybrid model — most common in 2026
IACall as the first layer (answers, qualifies, books, records); a human only for sensitive or VIP cases the agent flags.
