Nextiva remained the closest follower at 63.9% in August 2026, little changed from 63.0% in July 2026, leaving a gap of 3.0 percentage points between the two leaders.

The largest coverage decline belonged to Phone.com, which fell to 2.7% in August 2026 from 5.8% in July 2026, a move beyond normal month-to-month variation.

Research Scope and Qualification

The public benchmark is narrower than the raw collection universe by design. Brand-level percentages use the qualified observations as the public denominator, not the raw collection.

Research stage	Jul 2026	Aug 2026	What it represents
Source prompt-surface observations	800	800	Total prompts collected across AI/search surfaces
Unique questions	507	555	Distinct questions after deduplication
Brand / competitor mentions	800	800	Prompts mentioning at least one tracked brand
Relevant observations	791	790	Prompts relevant to the VoIP Services category
Irrelevant observations	9	10	Prompts outside the category scope
Qualified benchmark observations	587	626	Public denominator after all qualification steps

RingCentral	93.3%	66.9%	54.3%	32.4%	0.7

magicJack	7.0%	3.2%	1.6%	0.2%	0.3
Phone.com	7.8%	2.7%	0.5%	0.0%	0.3

RingCentral holds a 32.4% rank-one rate, while Nextiva sits at 11.3%, meaning close coverage rates still hide very different first-choice positions. The trailing cluster of GoTo Meeting, magicJack, and Phone.com shows minimal top-three or first-position presence.

How to Read the Standings

Presence rate: share of qualified observations where the brand is mentioned at all.
Valid recommendation coverage: share of qualified observations where the brand receives a valid recommendation.
Top-three rate: share of qualified observations where the brand appears in the top three recommendations.
Rank-one rate: share of qualified observations where the brand is the first recommendation.
Net sentiment: positive mentions minus negative mentions, divided by total mentions, ranging from -1 to +1.

Recommendation Coverage Movement

Brand	Jul 2026	Aug 2026	Movement since baseline
8x8	24.7%	20.8%	Down 3.9 points
Dialpad Meetings	40.2%	41.2%	Up 1.0 points
GoTo Meeting	4.8%	5.6%	Up 0.8 points
Grasshopper	36.5%	32.1%	Down 4.4 points
magicJack	3.9%	3.2%	Down 0.7 points

RingCentral	67.0%	66.9%	Down 0.1 points
Vonage	35.8%	34.2%	Down 1.6 points

Largest Decline: Phone.com

Phone.com posted the only significant coverage movement in August 2026. Its valid recommendation coverage fell to 2.7% in August 2026 from 5.8% in July 2026, a decline beyond normal month-to-month variation. Top-three placement also fell to 0.5% in August 2026 from 2.2% in July 2026.

Category Leader: RingCentral

RingCentral held the category lead with 66.9% valid recommendation coverage in August 2026, essentially flat against 67.0% in July 2026. Its rank-one rate fell to 32.4% in August 2026 from 38.5% in July 2026, even as its overall coverage rate held steady.

Recommendation Placement Snapshot

Coverage alone does not show how prominently a brand is recommended. The two leading brands show different placement profiles.

Brand	Aug 2026 top-three rate	Aug 2026 rank-one rate	Jul 2026 top-three rate	Jul 2026 rank-one rate
RingCentral	54.3%	32.4%	56.7%	38.5%
Nextiva	47.4%	11.3%	49.2%	10.6%

RingCentral and Nextiva both hold high top-three rates, but RingCentral leads in first-position placement, even after its rank-one decline from July to August 2026. Close coverage rates can still hide different first-position rates.

Buyer-Intent Distribution

The qualified observations in both months fell into the Brand Recommendation class, covering discovery and consideration queries.

Buyer-intent class	Jul 2026	Aug 2026
Brand Recommendation	587	626
Pricing & Value	0	0
Multi-Brand Comparison	0	0
Total qualified observations	587	626

The current public series measures the Brand Recommendation class of discovery and does not yet contain qualified observations in the Pricing & Value or Multi-Brand Comparison classes.

Historical Measurement Record

This is an evergreen benchmark URL. New measurements are added to the same report.

Measurement	Qualified observations	Coverage leader	Leader coverage	Largest coverage movement
Jul 2026	587	RingCentral	67.0%	Baseline period
Aug 2026	626	RingCentral	66.9%	Phone.com, Down 3.1 points

Evidence and Source Layer

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure:

Market share or revenue attribution.
Every possible AI response across all models and configurations.
Organic search ranking performance.
Social media mention volume.
Private or sponsored channels.
Causality from a metric movement alone.
