# Evaluating enterprise messaging + voice alternatives

> A tenant-owned scoring rubric for enterprise messaging and voice platforms (Twilio, Vonage, Sinch, Plivo, Devotel Orbit): the checklist rows, a worked scoring table, evaluation surfaces, and the FAQ on when not to move.

# Evaluating enterprise messaging + voice alternatives

Enterprise messaging-and-voice evaluations come down to one question: whether the numbers, the sender registrations, and the consent records live in your account. This page gives you the checklist, a worked scoring table for Twilio, Vonage, Sinch, Plivo, and Devotel Orbit, the surfaces to run the evaluation on, and an FAQ for deciding when the incumbent should stay.

## 1. Gaps buyers hit first

* **Carrier and BYO lock-in.** The incumbent holds your numbers in its own account, so porting out means a vendor-mediated ticket rather than a tenant-initiated export. Score the escape hatch before you sign, not when you need it.
* **Opaque per-message pricing.** The bill arrives as one blended line item because the vendor marks up per-country rates without publishing them. If you cannot model your volume against the same surface a signed tenant bills on, the comparison grid you read is fiction.
* **Split SMS and voice contracts.** Messaging and voice bought as two products — two contracts, two dashboards, two support queues — doubles the procurement surface and splits every conversation record across silos.

Orbit closes these with tenant-owned surfaces: [SMS](/channels/sms) and [voice](/channels/voice) on one account, a published [pricing surface](https://orbit.devotel.io/pricing) to model volume against, and tenant-held numbers you can [port out](/numbers/porting) from your own account.

## 2. Tenant-owned checklist rows

Score every candidate on four rows you can verify about any vendor:

* **Number ownership.** Number inventory lives in the tenant's own account and ports out on tenant initiation — [Buy numbers](/guides/buy-numbers) and the [port-out flow](/numbers/porting), not a vendor-rented pool.
* **Sender registration ownership.** The campaigns and sender identities the registration regimes (US 10DLC, India DLT, international alphanumeric sender IDs) bind to your brand live in your account — [10DLC registration](/guides/10dlc-registration) and the [sender-ID registration](/compliance/sender-id-registration) surface.
* **Consent posture.** Per-recipient consent and suppression records are tenant-owned objects you govern, with the audit trail your organization sets — [Consent management](/compliance/consent-management).
* **Auditability.** Configuration and assignment exports come through the API on your own key, not through a support ticket — [audit export](/compliance/audit-export).

## 3. Scored candidates

Score each candidate "yes / partial / no" per row, at the level of the published product surface; a blank cell reads as missing research, so mark "partial" or "no" instead of leaving one.

| Checklist row                 | Twilio                                                                            | Vonage                                            | Sinch                                             | Plivo                                             | Devotel Orbit                                                  |
| ----------------------------- | --------------------------------------------------------------------------------- | ------------------------------------------------- | ------------------------------------------------- | ------------------------------------------------- | -------------------------------------------------------------- |
| Number ownership              | partial — numbers held in the vendor's account, port-out through vendor mediation | partial — same vendor-held pool                   | partial — same vendor-held pool                   | partial — same vendor-held pool                   | yes — tenant-provisioned numbers you port out self-serve       |
| Sender registration ownership | partial — 10DLC/DLT registered per vendor campaign object                         | partial — registration tied to the vendor console | partial — registration tied to the vendor console | partial — registration tied to the vendor console | yes — registration objects in your account, retrievable by API |
| Consent posture               | partial — opt-out keywords handled at the vendor layer                            | partial — suppression managed per vendor          | partial — suppression managed per vendor          | partial — suppression managed per vendor          | yes — tenant-owned consent and suppression objects             |
| Auditability                  | no — configuration export needs a support path for several surfaces               | no — same support-ticket path                     | no — same support-ticket path                     | no — same support-ticket path                     | yes — self-serve API export of configuration and assignments   |

Read the table as a starting hypothesis: re-score the rows against a live trial of each candidate on the surfaces below, and keep the incumbent honest by running it through the same checklist.

## 4. Evaluation surfaces

Ground every claim from a vendor on the same surfaces you would run Devotel Orbit against:

* **Sandbox API key** — create a `dv_test_sk_` key from the dashboard with no KYC or approval step; simulated sends cost \$0. The [sandbox model](/guides/sandbox-test-mode) and the [magic-numbers playbook](/sandbox/magic-numbers) let you walk an end-to-end message or call flow before provisioning anything. Start from the [quickstart](/quickstart).
* **Channel docs as capability probes** — the SMS row maps to [channels/sms](/channels/sms), the voice row to [channels/voice](/channels/voice), the registration rows to [10DLC registration](/guides/10dlc-registration) and [sender-ID registration](/compliance/sender-id-registration), the consent row to [consent management](/compliance/consent-management), and the audit row to [audit export](/compliance/audit-export). If a capability matters to the decision, read the page a tenant configures it from.
* **Pricing page** — [orbit.devotel.io/pricing](https://orbit.devotel.io/pricing) is the same surface a signed tenant bills against; model your message and minute volume there instead of trusting a comparison grid.

Use the same surfaces for every candidate on your shortlist — the point of the checklist is that you own the verdict, wherever it lands.

## 5. When not to move — FAQ

**Should we move off the incumbent?**
Not when the incumbent is winning on its own merits: an existing committed-use contract priced below what a self-owned number inventory would cost at your volume, a compliant legacy aggregator whose integration is deep and whose replacement would burn a quarter of engineering time for no ownership gain, or a program that no audit will ever ask to prove chain-of-custody for. Run the checklist; if the ownership rows score "partial" on both sides, the move argument is weak.

**Do we have to give up the incumbent while we evaluate?**
No. Numbers, registrations, and consent export are additive evaluation work: provision a sandbox key, run the checklist surfaces, and port a single number only after the scoring table confirms the ownership rows have moved.
