When buyers ask AI engines about Voice over IP providers, RingCentral often emerges as the leader, showing up 50.0% of the time in their responses. Other top competitors include Nextiva and Zoom Phone. RingCentral's prominence in these recommendations highlights its strong position in the market.
The rankings are influenced by the frequency with which AI engines cite certain sources, like nextiva.com, pcmag.com, and youtube.com. These sources are often aggregator or review sites, which means they provide comprehensive comparisons and detailed analyses, contributing to the way AI engines make their recommendations.
For buyers, this page serves as a useful tool when selecting a brand. AI engines give weight to recent reviews and third-party validation, so consider these aspects when choosing from the list. Brands with significant visibility and topical authority in the subcategory might offer more reliable and up-to-date services.
At a glance
What we observed in this category
RingCentral leads the VoIP category with a composite score of 50.0, the only brand where visibility and citation are perfectly balanced at 50.0 percent each. Nextiva sits second at 45.0 composite but its citation rate of 62.5 percent already exceeds RingCentral's. The gap between first and third place (50.0 versus 35.0 composite) is significant, but the drop from third to fifth is steeper still, falling from 35.0 to 20.0, indicating a concentrated top tier with a long tail of weaker performers against a category average visibility of just 8.8 percent.
The most striking divergence between visibility and citation appears at rank 4, where Aircall holds zero percent visibility yet 75.0 percent citation, the highest citation rate in the dataset. Zoom Phone shows the inverse pattern, matching RingCentral at 50.0 percent visibility but recording zero citations. CloudTalk and SIP.US also carry zero visibility alongside citation rates of 37.5 and 25.0 percent respectively. This split reveals that being named in AI responses and being linked as a trusted source are operating as largely independent signals in this category.
Google AI Mode is the top engine for every brand in this dataset without exception. Among cited sources, nextiva.com and ringcentral.com appear directly alongside third-party review outlets pcmag.com and uk.pcmag.com, as well as crazyegg.com, reddit.com, and youtube.com. The presence of Reddit and YouTube suggests the AI is drawing on community and video content rather than relying solely on vendor or specialist press material. PCMag appearing in two regional variants signals strong editorial weight from that single publisher across this category.

How to read this AEO ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
AEO rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 90 days and refresh this page automatically. How AI search ranking works →
