Vonage was named in 4 of the 6 answers we collected for call center software, more than any other product, when we asked ChatGPT and Gemini for the best tool in the category. No product was named in all six. Three tools tied just behind it: Five9, Nextiva and TalkDesk each appeared in 3 of the 6 answers (50%).
We put six real buyer phrasings to ChatGPT and Gemini on 2026-08-03, gave each one live web search, and logged every product named and every source domain cited. That is the whole dataset on this page: six questions, six answers, 28 distinct product labels named in total, and nothing weighted by our opinion or by market share.
Who got named
Vonage sat on top at 4 of 6 (67%), and the chase pack was tight: Five9, Nextiva and TalkDesk at 3 of 6 (50%) each, then Aircall, CallHippo, LiveAgent and Zendesk at 2 of 6 (33%). Every other name, 20 product labels in all, was mentioned exactly once.
The biggest enterprise brands barely registered. Genesys Cloud CX and NICE CXone were each named in just 1 of the 6 answers (17%), and both only surfaced in the generic "recommendations" question. In this data, being a category giant did not earn a spot. Being in the right source did.
How the shortlist changed with the question
The shortlist was not one list, it was at least three, and they barely touched. The plain "best call center software" answer named seven products: Nextiva, Five9, TalkDesk, Vonage, Zendesk, LiveAgent and Dialpad AI. The "best free" answer shared zero of them.
Asked for the "best free call center software," the assistants returned a completely different eight: Webex Suite, Freshdesk, Zoho Desk, Bitrix24, CallHippo, ActivTrak, Agile CRM and Salesforce Service Cloud. Six of those (Webex Suite, Freshdesk, Zoho Desk, Bitrix24, ActivTrak and Agile CRM) appeared in that one free question and nowhere else across the six.
"Most affordable call center software" produced a third set of five: Twilio Flex, Nextiva, RingCentral, Avoxi and CallHippo. Three of them (Twilio Flex, RingCentral and Avoxi) showed up only in the affordable question. CallHippo was the single product named in both the free and the affordable answers, the one bridge between the two budget framings, at 2 of 6 overall.
Vonage tells the story best. The overall leader at 4 of 6 never once appeared in the free or the affordable answer. It was named in "best," "small teams," "what should I use" and "recommendations," every quality-first framing, and vanished the moment a buyer typed "free" or "affordable." Those two budget words wiped out the premium names and swapped in a bench the generic query never mentions.
The narrower questions had their own one-time names too. "Small teams" was the only place Dialpad, 8x8 and Bright Pattern came up (1 of 6 each). "What should I use" was the only home for QEval and Dialpad AI Contact Center. "Recommendations" was where Genesys Cloud CX, NICE CXone, 8x8 Contact Center and Salesforce made their single appearances. If you tracked only "best call center software," you would be blind to most of your own category's answers.
Where the answers came from
Two domains fed every single answer: getvoip.com and reddit.com, each cited in 6 of 6. Quora was close behind at 5 of 6 (83%). The answers leaned on one telecom roundup site and two community forums before anything else.
On review directories specifically: yes, they appeared, but unevenly. G2 was cited in 4 of the 6 answers (67%), plus its learn.g2.com subdomain in 1 more, while Capterra showed up in just 1 of 6, the free question. Reddit at 6 of 6 and Quora at 5 of 6 were both cited more consistently than either directory.
Here is the part a vendor should read twice. Several tools had their own website cited as a source and got named in the same answer. Vonage is the clearest case: vonage.com was a source in the small-teams answer, and Vonage was named in that same answer plus three others, 4 of 6 overall. Zendesk shows it twice over: zendesk.com fed both the "best" and the "what should I use" answers, and Zendesk was named in both. Nextiva, Aircall, Salesforce, Bitrix24, Bright Pattern and Avoxi each had their own domain cited in an answer that named them. Owning a page the assistant reads, and sitting in the roundups, tracked with getting named.
It is not automatic, though. Three vendor domains were cited without the vendor being named at all: ringover.com, verint.com and ximasoftware.com each fed one answer, and each of those pages recommended other tools, so Ringover, Verint and Xima were sources but never made a single shortlist. A comparison post on your own blog can get you cited and still hand the recommendation to a rival.
What we would do to get named here
If we sold call center software, we would not chase market share, we would chase four specific sources. getvoip.com and reddit.com fed 6 of 6 answers, Quora 5 of 6, G2 4 of 6. A product that is reviewed on G2, discussed in the right Reddit threads, and listed in the getvoip roundups is sitting in the exact pages ChatGPT and Gemini read back to buyers. That is why Vonage at 4 of 6 outranked Genesys Cloud CX and NICE CXone at 1 of 6: source presence, not company size, set the order.
The budget queries are a separate job. To get named for "free" or "affordable" you need a different source set: the getvoip and Capterra free-tool roundups, the CXLead list (thecxlead.com fed the free answer), and vendor free-tier pages like bitrix24.com that the free question pulled from. None of the premium-query sources carried into the budget answers, so a vendor watching only "best [category]" would never see the free shortlist it is missing.
The full list, counted
One caution before the table: the assistants logged some vendors under more than one label, and we have not merged them, because the raw data never shows a combined number. Dialpad appears three separate times (Dialpad, Dialpad AI and Dialpad AI Contact Center), 8x8 twice (8x8 and 8x8 Contact Center), and Salesforce twice (Salesforce and Salesforce Service Cloud). Each row is counted exactly as the measurement recorded it.
| Product | Named in | Share |
|---|---|---|
| Vonage | 4 of 6 | 67% |
| Five9 | 3 of 6 | 50% |
| Nextiva | 3 of 6 | 50% |
| TalkDesk | 3 of 6 | 50% |
| Aircall | 2 of 6 | 33% |
| CallHippo | 2 of 6 | 33% |
| LiveAgent | 2 of 6 | 33% |
| Zendesk | 2 of 6 | 33% |
| Dialpad | 1 of 6 | 17% |
| Dialpad AI | 1 of 6 | 17% |
| Dialpad AI Contact Center | 1 of 6 | 17% |
Beyond the rows above, 20 product labels were each named once (17%). The three Dialpad labels are among them; the rest include 8x8, 8x8 Contact Center, Genesys Cloud CX, NICE CXone, Twilio Flex, RingCentral, Avoxi, Bitrix24, Freshdesk, Zoho Desk, Webex Suite, Salesforce, Salesforce Service Cloud, Bright Pattern, ActivTrak, Agile CRM and QEval.
Why Glotier is not on this list
Glotier does not sell call center software, so we are correctly absent from all 6 of these answers. We were not named, and we would not expect to be: this is not our category to be recommended in, and we are not going to pretend otherwise.
But running this check is exactly what Glotier does for the category that is yours. The same six-question measurement, the same product and source counts, pointed at your market, shows which pages ChatGPT and Gemini read before they answer and whether your name is in them. It is free, needs no account, and takes about a minute.
