How AI Search Is Recommending VoIP Services: Monthly Trends

Executive Summary

RingCentral extended its lead in AI search recommendations for VoIP services, holding 73.5% valid recommendation coverage in October 2026, up 6.5 points from 67.0% in July 2026. The gap to the next brand, Nextiva at 68.9%, widened slightly to 4.6 points as both leaders moved up together.

The strongest riser over the series is RingCentral, which combined a 6.5 point coverage gain with a 10.8-point rise in top-three rate and a rank-one rate that rose 6.0 points to 44.5%. Nextiva also posted a significant gain, up 5.9 points from 63.0% in July to 68.9% in October. Phone rose 1.4 points to 1.4% on a small base.

The sharpest declines over the same period sit in the middle and lower tiers. Grasshopper fell 8.7 points from 36.5% in July to 27.8% in October, a significant decline that extended across three consecutive months. Phone.com fell 5.8 points from 5.8% to 0.0% and recorded no valid recommendations in October.

Against the prior month, the category shifted. RingCentral rose 7.5 points from September, Nextiva rose 5.8 points, and 8x8 rose 6.1 points, all above normal variation. The leadership position was already held by RingCentral; what changed is the size of the lead and the wider spread between the top two and the brands below them.

Each monthly run begins with 800 prompt-surface observations across the benchmark's defined AI/search surface universe. In July 2026, those 800 prompts contained 507 unique questions; 800 mentioned a tracked brand or competitor, 791 were relevant and 9 were irrelevant, and the public metrics used the 587 qualified observations. In October 2026, the same 800 prompts contained 534 unique questions; 800 mentioned a tracked brand or competitor, 770 were relevant and 30 were irrelevant, and the public metrics used the 633 qualified observations. August and September 2026 followed the same funnel structure, with 626 and 651 qualified observations respectively.

Key Findings

AI Response Inconsistency Alerts

Three critical or high-severity factual inconsistencies were detected across three AI platforms in October 2026. All three involve conflicting pricing claims, and all three centre on Nextiva.

Nextiva

AI platforms provided conflicting information about the monthly price for Nextiva's Core plan. When asked "Is Nextiva a good phone service?", Google AI Mode stated that Core costs $23 to $30 per user per month, while ChatGPT stated that Core starts at $15 per user per month on annual small-business pricing. Google AI Mode cited the company's blog reviews page, Business.com, and Crazy Egg; ChatGPT cited the company's pricing page, G2, and Capterra. Flagged sources included the company's pricing page, which displayed "$15/user/mo" alongside a $23 figure, and a Grasshopper comparison page stating "Core Plan: From $15/user/month (billed annual)."

Responses also differed on Nextiva's overall monthly price. When asked "Which is the best VoIP company?", Gemini stated a starting price of approximately $23 per user per month, while ChatGPT stated that Core pricing starts at $15 per user per month when billed annually and that Engage is $25 per user per month. Gemini cited withallo.com, Crazy Egg, and PCMag; ChatGPT cited RingCentral's plans and pricing page, the company's small-business VoIP product page, and Zoom's VoIP phone page. Flagged sources included a Crazy Egg page citing "$15 per user/mo" and the company's own small-business VoIP page showing both a $15 and a $23 figure.

AI platforms also provided conflicting information about the monthly price for Nextiva's Engage plan. When asked "Is Nextiva a good phone service?", Google AI Mode stated that Engage costs $50 to $55 per user per month, while ChatGPT stated that Engage costs $25 per user per month. Google AI Mode cited the company's blog reviews page, Business.com, and Crazy Egg; ChatGPT cited the company's pricing page, G2, and Capterra. Flagged sources included a Grasshopper comparison page stating "Engage Plan: From $25/user/month (billed annual)" and the company's pricing page, which displayed "$25/user/mo" alongside a $50 figure.

Benchmark Context

The report separates the raw collection universe from the qualified analysis set. Brand-level recommendation percentages are calculated within the qualified benchmark set.

The qualified observation count moved from 587 in July to 633 in October, with August at 626 and September at 651. The eligible set peaked in September before settling in October, and the irrelevant count rose to 30 in October from 9 in July.

Benchmark-Level Metrics

The recommendation-shaped answer share moved sharply across the series, from 45.7% in July to 40.3% in August, then 45.3% in September before climbing to 61.3% in October. The valid recommendation shortlist share peaked at 78.4% in October after ranging between 68.0% and 69.8% across the prior three months.

AI Recommendation Trend

Questions This Section Answers

• Who holds the top positions in AI recommendations for VoIP services, and how did the July-to-October gap change?
• Which VoIP brands gained or lost the most recommendation coverage over the series?

Leaders Pull Away From a Thinning Middle

RingCentral and Nextiva hold the top two positions by valid recommendation coverage, with Ooma in third. The gap between the leaders and the mid-tier widened this month as RingCentral and Nextiva each posted significant gains while most brands below them held flat or declined.

Over the July to October series, both significant gains were concentrated at the top. RingCentral and Nextiva each moved beyond normal month-to-month variation, while the category-level change below them came from the combination of several smaller movements and one significant decline, Grasshopper.

What Changed This Month

Questions This Section Answers

• What drove RingCentral's wider lead in October, and did mention presence or recommendation strength matter more?
• How did Nextiva's coverage gain differ from its top-three placement, and did pricing inconsistencies appear in those answers?
• Where did Grasshopper lose the most ground, and did it drop out of mentions or just rank lower when mentioned?

RingCentral: Widening lead on coverage, placement, and rank-one

RingCentral's valid recommendation coverage rose 6.5 points from 67.0% in July 2026 to 73.5% in October 2026, a significant gain over the full series. Against the prior month, coverage rose 7.5 points from 66.0% in September, also significant.

In absolute terms, RingCentral earned 465 valid recommendations in October 2026 across 633 observations, up from 393 of 587 in July. Its top-three rate rose 10.8 points from 56.7% to 67.5%, and its rank-one rate rose 6.0 points from 38.5% to 44.5%, both significant over the series.

The distinction to notice: RingCentral's gain is not just presence. Raw mention presence rose only 1.5 points to 95.4%, within normal variation. The movement is in recommendation strength: the brand is being converted from mention to top-three and rank-one placement at higher rates than in July.

Highest-priority diagnostic: Which prompt categories flipped from lower placement to rank-one, and are those same prompts where competing brands lost ground?

Nextiva: Significant coverage gain with top-three relocation

Nextiva's valid recommendation coverage rose 5.9 points from 63.0% in July 2026 to 68.9% in October 2026, a significant gain over the series. Against the prior month, coverage rose 5.8 points from 63.1% in September, also significant.

In absolute terms, Nextiva earned 436 valid recommendations in October 2026 across 633 observations, up from 370 of 587 in July. Its raw mention presence rose 4.5 points to 88.5%, and its top-three rate rose 8.0 points from 49.2% to 57.2%, both significant. Its rank-one rate rose 1.1 points to 11.7%, within normal variation.

The distinction worth noting: Nextiva closed the coverage gap to RingCentral slightly but widened its top-three gap. Coverage moved from 4.0 points behind RingCentral in July to 4.6 points behind in October, while Nextiva's top-three rate, at 57.2%, remains 10.3 points below RingCentral's 67.5%. Nextiva is recommended more often; RingCentral is recommended first more often.

Highest-priority diagnostic: Which prompts moved Nextiva into recommendations that previously excluded it, and does the pricing inconsistency documented above appear in any of those answers?

Grasshopper: Three-month decline with mention loss outpacing coverage

Grasshopper's valid recommendation coverage fell 8.7 points from 36.5% in July 2026 to 27.8% in October 2026, a significant decline. The fall continued in October, down 0.9 points from 28.7% in September, within normal variation for that single month but part of a three-month downward streak.

In absolute terms, Grasshopper earned 176 valid recommendations in October 2026 across 633 observations, down from 214 of 587 in July. Its raw mention presence fell 12.2 points from 46.2% to 34.0%, a significant decline. Its rank-one rate rose 1.5 points to 3.2% over the series.

The distinction that matters: Grasshopper is being named first somewhat more often in the answers that still include it, but it is being left out of far more answers overall. The presence decline is much larger than the coverage decline, which means the brand is losing ground at the mention stage, before recommendation placement is even applied.

Highest-priority diagnostic: Which prompt categories stopped mentioning Grasshopper, and which competitor appears in the answers where Grasshopper is now absent?

Phone.com: Coverage falls to zero, Phone enters

Phone.com's valid recommendation coverage fell 5.8 points from 5.8% in July 2026 to 0.0% in October 2026, a significant decline. In October 2026 the brand recorded no valid recommendations across 633 observations, down from 34 of 587 in July. Its raw mention presence fell from 10.1% in July to no qualified observations in October.

Against this, a brand listed in the benchmark as Phone entered the coverage table in October 2026 at 1.4%, up 1.4 points from a baseline of 0.0% in July, a significant gain on a small base. In absolute terms, Phone earned 9 valid recommendations in October 2026 across 633 observations, with 16 brand-presence observations.

The distinction worth flagging: these appear to be separate entries in the benchmark rather than a rename or a transfer. The category now tracks both, and Phone.com's decline has not been offset by Phone's appearance at the same scale. Both operate on small observation counts and should be read with that context.

Highest-priority diagnostic: For Phone.com, is the zero-coverage month a one-month reset or the end of a longer presence decline? For Phone, is the October entry the start of a durable presence or a single-month appearance on a small base?

8x8: Coverage recovers, top-ten presence does not

8x8's valid recommendation coverage rose 0.1 points from 24.7% in July 2026 to 24.8% in October 2026, within normal variation over the series. Against the prior month, however, coverage rose 6.1 points from 18.7% in September, a significant gain.

In absolute terms, 8x8 earned 157 valid recommendations in October 2026 across 633 observations, up from 122 of 651 in September and roughly level with 145 of 587 in July. Its raw mention presence fell 1.0 point to 34.6% over the series but rose 3.9 points against September.

The distinction to notice: 8x8's coverage has returned to its July level, but the composition has shifted. Top-three rate rose 0.9 points to 6.5% over the series while top-ten rate fell 1.2 points to 23.4%, suggesting the brand is more concentrated in higher placements when it appears but appearing in fewer answers overall. The single-month rebound from September should be read against the earlier September drop.

Highest-priority diagnostic: Which surfaces drove the September dip and the October recovery, and are the same prompts involved in both?

Buyer-Intent Interpretation

Questions This Section Answers

• Which buyer-intent clusters did the October qualified observations actually cover?
• What pricing, value, or head-to-head comparison questions can the public VoIP benchmark not settle?

In October 2026, the 633 qualified observations fell into the Brand Recommendation cluster. The public benchmark did not capture qualified observations in the Pricing & Value or Multi-Brand Comparison clusters. The current metrics describe which brands AI systems recommend for VoIP services, but they do not yet answer which brand wins on price, value, or head-to-head comparison at the qualified-observation level.

The pricing inconsistencies documented in the AI Response Inconsistency Alerts section show that pricing content does appear in AI answers, but those answers sit outside the qualified recommendation set and are not reflected in the coverage figures. Questions about which brand is cheaper, which plan offers better value, or which provider wins a specific head-to-head remain outside what the public coverage metrics can settle, and require a prompt-level analysis.

Brand Opportunity Summary

Questions This Section Answers

• Which VoIP brands show the strongest coverage signals, and which need attention?
• What prompt or evidence gap matters most for brands like RingCentral, Nextiva, Grasshopper, or Phone.com?

The benchmark identifies where attention is warranted; a company-level analysis is needed to explain why.

Evidence Behind the Benchmark

The aggregate metrics are built from prompt-level observations (query, surface, recommendation outcome, rank, sentiment, and citations where exposed). Company-level analysis can go deeper into prompt, competitor, surface, and evidence patterns. Source presence is not automatically treated as proof of causation.

The AI Response Inconsistency Alerts in this report draw from cross-platform prompt responses and the sources those platforms cited. Conflicting figures across platforms do not by themselves establish which figure is correct, nor do they establish which source is authoritative.

Report-Specific Interpretation Notes

• Small-count movement: Phone, magicJack, GoTo Meeting, and Phone.com operate on small absolute counts; their percentage movements should be read with that context in mind.
• Qualified denominator vs raw collection: all brand-level percentages are calculated within the 633 qualified observations, not the 800 raw prompts.
• Directional analysis: movement across the July to October series identifies changes worth investigating; it does not by itself establish the cause of those changes.

Next Step

The Public Benchmark Shows Where a Brand Is Winning or Losing. A Company-Level Audit Shows Why.

Beneath the aggregate percentage sit specific questions: which high-intent prompts are won, which competitor takes the recommendation when a brand loses, what attributes AI systems associate with each option, and which external sources shape those answers. For RingCentral and Nextiva, the diagnosis requires knowing which prompts flipped into stronger placement. For Grasshopper and Phone.com, it requires knowing which prompts dropped out and what replaced them.

The public percentage cannot identify the prompts, competitors, or sources causing the result. A company-specific AI visibility audit maps those prompt, surface, competitor, ranking, sentiment, and evidence-source patterns into a prioritized visibility strategy. It turns a benchmark signal into an actionable plan.
