SIP Tenders

Two routes. Watch the portals for notices with SIP in the title, which is the smaller half of the market, or search the descriptions, where most of it actually lives. Stotles aggregates 100+ portals and indexes the full notice text, so a telephony contract that mentions SIP only in its requirement detail still surfaces. Platform-wide, 5,226 notices are open right now.

Because SIP is a component, not a category. Buyers procure "telephony services", "fixed voice" or "unified communications" and specify SIP trunks inside the requirement. Of the 50 most recent notices matching this page's filter, most carry a title that never says SIP. Reading descriptions is the only way to find them.

SIP work sits in the telecoms services branch of the vocabulary. Alongside this page's keyword filter, CPV 64200000 (Telecommunications services) appears on 88 matching notices and 64215000 (IP telephone services) on 49. Neither is applied as a filter here: plenty of on-intent notices carry a broader IT code instead, or no code at all.

No. VoIP is voice carried over IP. SIP is the signalling protocol that sets those calls up and tears them down. In procurement the two words often land in the same notice, so a supplier chasing trunk work should watch the broader voice and telecom pages too. This page filters on SIP-specific phrasing only, which is why it returns 420 notices rather than everything tagged telecoms.

Most of it. Of the 420 notices under this filter, 261 are awarded contracts and 33 sit at pre-tender or planning stage. Open tenders are a thin slice at any one moment, so the awarded set is where the useful detail is: who bought, from whom, and when the term ends. Platform-wide, 2,178 award notices were published in the last seven days.
