What is the best Salesforce-native CTI?

What native actually means here

"Native" is not one thing. A Salesforce phone tool can be native on some layers and external on others, so the honest way to read the field is layer by layer. There are four.

The four layers of native

No vendor runs live call audio or large-model AI inside Salesforce; the platform cannot host either. So "native" is really about the first two layers, plus how honestly a vendor describes the last two.

The genuinely-native field

These run as a managed package and write records to Salesforce objects. Where they differ is recordings, AI, pricing, and the org size they are built for.

Revenue.io. Best for enterprise revenue orchestration. Records are native and its real-time AI coaching runs live on the call, not just as a post-call summary, but the dialer, telephony, and AI run on Revenue.io's cloud, pricing is quote-only with a 15-seat minimum, and AI sits in the higher tiers. Built for 15-rep-plus teams.

Natterbox. Best for enterprise voice and routing. The cleanest "no middleware" marketing in the field, with a managed package and records written to Salesforce, but the call recordings sit in Natterbox's own AWS storage, and the AI is gated to its Enterprise tier.

Fastcall. Best for a budget-minded native team. Built on Apex and Lightning, with call metadata logged to native objects. The trade-offs: the call audio sits in a Fastcall-provisioned Twilio, AI is rented through Einstein or Twilio rather than included, and there is a 10-seat minimum.

360 CTI. A native control plane with an external carrier. Records run through a managed package, but pricing is quote-only, AI is a separately branded add-on, and the CTI product itself carries few independent AppExchange reviews to check the claim against.

PhoneIQ. Native user experience, not native data. PhoneIQ embeds through an Open CTI adapter, and the phone system, recordings, and AI run in PhoneIQ's cloud, with recordings pushed back into Salesforce. "Built for Salesforce" here means the interface, not where the data lives.

WorkDial. Best for the Salesforce-only SMB. Records are native, AI call analysis is included in the seat, telephony is your own Twilio at carrier cost, and recordings go where you choose: as native Salesforce Files in your own org, in your own Twilio, or in your own cloud storage. WorkDial keeps no copy of its own.

How to choose

"Native" is now table stakes; several vendors clear the first two layers. The differences that decide it are five questions, and the answers are easy to check on any vendor's own pages.

1. Is AI included, or an add-on? Call analysis is where most of the daily value is. Ask whether transcripts, sentiment, and summaries are in the seat or a separate line item.
2. Can you bring your own telephony at cost? Bring-your-own-Twilio means you pay carrier rates directly, with no markup on minutes, instead of buying resold minutes.
3. Does the vendor keep a copy of your data? Ask where the call recordings physically live, and whether you can choose your own org or account instead of a vendor store.
4. Can it place the calls your team makes? If you run outbound, confirm there is a real outbound dialer, not just inbound or click-to-dial.
5. Is the price published? A flat, published per-seat price with a real trial tells you more than a quote-only enterprise plan.

Where WorkDial fits

WorkDial is built for the Salesforce-only org of 20 to 250 employees, running 5 to 50 seats, that wants AI call analysis in the seat, its own telephony at cost, and call recordings it controls, at a flat $$28, $$59, or from $$99 per user per month.

It is not the pick for a 250-seat-plus contact center that needs deep workforce management and revenue orchestration; that is Revenue.io or Natterbox territory, and they earn it. WorkDial wins on the SMB combination none of them match: records native, AI included, your own Twilio, and recordings you keep. Native is the credential. The combination is the reason.
