CallUltra vs ElevenLabs
The strongest voice synthesis in the category, with a deliberately model-neutral agent framework layered on top.
The short version
ElevenLabs has better voices and a much deeper agent framework than we do. They do not sell phone numbers. You bring Twilio or your own SIP trunk and reconcile a second bill. We provision the number, meter it and bill it inside the product, in rupees, with the telephony included in the rate.

Where CallUltra is stronger
We sell you the phone number
ElevenLabs’ batch-calling documentation states that numbers must be imported via a Twilio integration or SIP trunking. An Indian team must bring its own carrier, complete number KYC separately with that carrier, and reconcile two bills. CallUltra provisions the number, reserves the funds, debits the wallet and releases the number at the carrier if rental goes unpaid.
One rate, in rupees, telephony included
Their pricing page states that the LLM and any telephony bill separately on top of the per-minute rate, so the advertised figure is one component of three and a buyer cannot compute the total from the page. USD-billed platforms typically stack to ₹10-₹16/min once FX and Indian termination are added.
Language can change during the call
ElevenLabs documents language selection as fixed for the duration of a call. On a Hinglish call that is a concrete functional limit.
An outbound operations layer
Lead lifecycle, a retry-approval queue where exhausted attempts wait for a human decision, and disposition write-back, an operations surface ElevenLabs deliberately does not build.
Where ElevenLabs is stronger
Voice quality, and it is genuinely hard to match
Thousands of voices, strong voice cloning, and an expressive conversational mode with real-time emotional adaptation. Naturalness is the consistent theme in their public reviews. CallUltra offers 30 fixed voice personas and no cloning at all.
A real agent framework, not a prompt wrapper
Subagent nodes, dispatch tools with explicit success and failure edges, deterministic and model-driven edge conditions, retry loops, agent versioning with branches, and a simulation suite. Our equivalent flow compiler has no editor UI behind it.
Model neutrality
Bring your own LLM: OpenAI, Anthropic, Google or your own endpoint. CallUltra runs one model, and our model picker does not currently change it.
Which one should you pick?
Choose ElevenLabs if…
Choose ElevenLabs if you are embedding a voice agent into a web or mobile product where voice quality is the product and telephony is incidental, or if you need voice cloning, a visual agent framework, or your own LLM.
Choose CallUltra if…
Choose CallUltra if you are an Indian team running outbound campaigns from a lead list and you want the platform to own the phone number, the rupee billing and the CRM write-back.
Pricing
CallUltra starts at ₹2,999/month with 300 AI minutes included, rising to ₹14,999 for 2,100 minutes and 20-way concurrency. Overage runs from ₹5 down to ₹3.75 a minute depending on tier, and telephony is included in the rate. Minutes are counted only once the callee answers.
ElevenLabs lists $0.080/min overage, with burst usage at double rate and reduced processing priority. Their page states explicitly that LLM tokens and telephony are additional, so the loaded cost for an Indian outbound campaign is meaningfully higher than the headline.
Pricing read 24 August 2026. Compare loaded cost rather than headline rate, several vendors in this category exclude telephony, language-model usage or both from the advertised per-minute figure.
Common questions
Can ElevenLabs make phone calls in India?
Yes, but you must supply the telephony yourself, their documentation requires importing a number through Twilio or connecting your own SIP trunk. You complete number KYC with that carrier separately and reconcile two bills. CallUltra provisions and bills the number inside the product.
Does CallUltra support voice cloning?
No. CallUltra offers 30 fixed voice personas across 16 languages. If a cloned or custom-trained voice is a requirement, ElevenLabs is the better choice.
