digium.com website review

40 files block the first paint until they finish downloading. Deferring or inlining them could save about 6.7 s.

About 644 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.1 s faster on a phone.

The page has 16,155 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

5 files are served with short cache lifetimes, so returning visitors download them again (280 KiB).

Your mobile performance score is 48. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

151 KiB could be saved by minifying JavaScript.

5 third-party services load with your homepage (Usercentrics CMP, star2star.com and Google Fonts and others), adding 911 KiB and 807 ms of main-thread time.

Usercentrics CMP costs a phone 669 ms of main-thread work and 256 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

About 37 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

Polyfills for old browsers add 34 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 350 ms faster on a phone.

11 long tasks block the main thread while loading, the longest for 308 ms. During a long task the page ignores taps.

7 images could be 294 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

A phone's processor spends 2.8 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

The first text or image appears after 10.1 s on a phone. Good is under 1.8 s.

Your largest element takes 14.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Affordable, essential business communications with scalable…”.

Visually, the page fills in at 10.1 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 14.3 s. Good is under 3.8 s.

Real visitors wait 3.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.8 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.5 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 340 ms in total while the page loads. Good is under 200 ms.

6 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 83 ms to 80 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 2.0 s to 2.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 22.3 MB in 156 requests on a phone: media 18.9 MB (5), images 1.6 MB (63) and scripts 1.5 MB (58). Under 2 MB keeps phones on slow connections fast.

1 image (66 KiB) is JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 6.33 g of CO₂e: 759.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

8 visible links have no text or label, so screen readers cannot say where they go.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

There is no <h1>, so neither visitors nor Google get a clear main headline.

11 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 1,041 pages on digium.com and 137 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

/teamhub, /products/5g-wireless-access, /products/open-source and /microsoft-teams-integration have no meta description, so Google writes the search snippet from whatever text it finds.

/teamhub and /products/business-collaboration/video-conferencing have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 43 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

Chrome logged issues while loading the page (“Cookie”).

Large scripts ship without source maps.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

sangoma.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage carries about 907 words of visible text.

DMARC is set to p=none, so mail pretending to be digium.com is still delivered. Reports are on, so moving to quarantine is the next step.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Opening the homepage sets 2 cookies (measured from a US location before any click).

Loading the homepage contacts 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
