Built to be embedded
The voice platform behind Atriam.
Atriam, the operations app for construction companies, runs every call and text on SiteCall. Your product can use the same API: numbers, calls, texts, routing and voice agents, with a separate workspace for each business you serve.

Security you can read.
Every workspace is isolated in the database, and a number's history stays with the business that used it. Our security page also lists what we don't claim.
