Numbers & DIDs, delivered as one portfolio.
Dollu holds direct numbering agreements with domestic carriers and regulators around the world, giving you geographic, national, mobile and toll-free numbers in more than 110 countries - including many where numbers are notoriously hard to source, such as India, the Gulf and parts of Africa.
Numbers are ordered, documented and activated from a single portal or API. Inbound calls are delivered over SIP to any endpoint you choose - your PBX, contact-centre platform, Microsoft Teams tenant or our own cloud voice stack - with routing rules, failover and recording configured per number.
We manage the regulatory paperwork, address validation and end-user KYC that each country requires, and we keep it current so your numbers stay live.
