This page aggregates measured, corroborated evidence: donors' iPhones recorded apps contacting this domain, every claim below was reported by separate accepted donations and published under a human verdict (later rows for an approved app inherit its verdict). A contact is a measurement, not an accusation — it does not show what data was sent.

What our research panel found AI-drafted · human-reviewed
We ask several independent AI models the same question and publish their answers separately — cross-vendor agreement is evidence against fabrication, and disagreement is worth seeing. 3 of 3 models answered, overall confidence high. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
The domain is a subdomain of ringcentral.com, which is the vendor of the RingCentral app (bundle id com.glip.mobile, formerly Glip), and the 'sip131-1111' hostname pattern is consistent with a SIP signaling/voice server used for the app's core calling functionality. A first-party call-signaling endpoint does not by itself imply a data flow beyond the app's stated function, so the empty privacy label is not evidence of an undisclosed third-party flow here.
OpenAI — first-party
The domain is under ringcentral.com and the bundle identifier indicates the RingCentral/Glip app, so it most likely supports the app's own communications service. No evidence is provided that this specific SIP contact entails collection or sharing requiring disclosure.
Google Gemini — first-party
sip131-1111.ringcentral.com belongs to RingCentral, the developer of the app, making this first-party operational traffic used for SIP communication functionality.
