Detailed Review
DIDWW's terms name DIDWW Ireland Limited of 25 North Wall Quay, Dublin as the operator of the service, and the same entity issues the privacy notice. The company also runs a telephony museum in Siauliai, Lithuania, which its about page mentions.
Unlike several sales-led carriers here, its pricing pages show a rate for a chosen country, with a downloadable price list and a quote form for larger volumes.
Rates you can read before talking to anyone
The SIP trunking pricing page lets a visitor pick a destination and shows the per-minute figure for local and international calls. For the United States it showed $0.004 per minute for local-ID calls and $0.0046 per minute for international ones on the day of checking.
Everything is quoted in US dollars, which a euro-based finance team should price in. A price list download and a custom quote option cover higher volumes.
Numbers and coverage
Besides trunks, the catalogue covers local, national, mobile, toll-free, shared cost and universal international freephone numbers, and the SIP trunk page lists termination in several hundred countries and territories. US numbers start at $1.20 per month.
Moving numbers in is described as free of charge, which removes one common reason to stay with an incumbent carrier.
Where the data goes
The privacy notice states that providing the service requires transferring data outside the EEA and names the USA, Singapore and Germany among the countries where it may be processed.
The terms also state that, unless agreed in writing, DIDWW infrastructure does not support or carry emergency calls, which matters for an office phone line.
Limitations to Consider
Prices are in US dollars rather than euros. The terms say emergency calls are not supported unless agreed in writing, even though a separate emergency calling product is listed. The privacy notice names the USA and Singapore among processing locations, so a European data-residency requirement needs a direct answer from the vendor. It is a supplier for technical buyers, with less hand-holding than sipgate or easybell.

Resellers, SaaS platforms and technically confident companies that want an Irish contracting entity, open per-minute rates and numbers in many countries.
