The short version

Each has a real cost: Ozonetel no pricing is published in any usable form, so seat rates, per minute charges, number rental and dialler licences are entirely opaque until a sales process is underway, which makes budget approval slow.; Telesign risk scoring is probabilistic, so tuning thresholds trades fraud caught against genuine users blocked, and somebody has to own that trade-off continuously.
They diverge on capability: Ozonetel covers Owned telecom infrastructure, Telesign covers Phone number verification.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Ozonetel

No pricing is published in any usable form, so seat rates, per minute charges, number rental and dialler licences are entirely opaque until a sales process is underway, which makes budget approval slow.
Contact centre cost in India is dominated by per minute telecom charges rather than seat licences, so a low quoted seat rate can hide the majority of the bill in usage that scales with call volume.
Feature depth outside voice is thinner than Genesys or Talkdesk, so an organisation prioritising digital-first omnichannel with deep workforce management will find gaps.
The product, support model and integration set are shaped around Indian market requirements, and organisations outside India get a smaller partner network and less mature local support.
On-premise deployment, one of its main selling points for regulated buyers, brings back infrastructure, upgrade and capacity planning costs that the move to cloud contact centres was meant to remove.

Telesign

Risk scoring is probabilistic, so tuning thresholds trades fraud caught against genuine users blocked, and somebody has to own that trade-off continuously.
No voice pricing is published at all: every one of the 233 destinations in its public rate card lists voice as quote only, so voice cost cannot be modelled in advance.
It is a verification and risk product, so a business that also needs general purpose messaging will run a second vendor for that traffic.
Number intelligence quality varies by country because it depends on operator data availability, and coverage in some markets is thinner than the global claim implies.
The underlying carrier assets belong to its sibling companies rather than to Telesign, so network questions route back to a parent whose principal business is not developer APIs.

Answered from the vendors’ own pages

Ozonetel: Does Ozonetel publish prices?

No. There is no working public rate card, and seat plus usage pricing is negotiated per account.

Telesign: Who owns Telesign?

Proximus, the Belgian telecommunications operator. It acquired Telesign in 2017 through its subsidiary BICS and has owned it outright since February 2021. Telesign now sits in Proximus Global alongside BICS and Route Mobile.

Ozonetel: Can it be deployed on-premise?

Yes. On-premise and private cloud deployments are offered, which is the main reason regulated Indian financial institutions choose it.

Telesign: Did Telesign go public?

No. A merger with the North Atlantic Acquisition Corporation special purpose vehicle was announced in December 2021 at around 1.3 billion dollars and terminated on 1 July 2022, so it remained within Proximus.

Ozonetel: What makes it different from a reseller?

Ozonetel operates its own telecom infrastructure in India rather than layering software over a third party carrier.

Telesign: Is Telesign a cheaper way to send one-time passcodes?

No, and that is not its purpose. It routes for verification completion and adds a risk judgement about the number. If you only need cheap message delivery, compare rate card vendors instead.

Ozonetel: Is voice the only channel?

No. WhatsApp and digital channels route into the same agent queues, though voice remains the strongest part of the product.
