Frequently Asked Questions

What is sipgate.io?

sipgate.io is the developer add-on to sipgate's German business telephony, and it is scoped narrowly on purpose: a REST API and webhooks for call control, SMS and fax, plus a Push API for real-time call events.

It is not a standalone CPaaS signup — sipgate.io requires an existing sipgate phone account, so this fits a team already using sipgate's cloud telephony and wanting to script around it, not a greenfield SMS or voice integration for an application with no telephony behind it.

Where is sipgate.io based?

sipgate.io operates from Düsseldorf, Germany, which places it under EU (Germany).

What does sipgate.io cost?

REST API free tier (S) with 100 free webhook calls then 4.9 cents each; M plan €4.95/month (2.9 cents/call); L plan €29.95/month (1.9 cents/call); XL custom; SMS at 9.9 cents net per 160-character message; requires an existing sipgate account. Free S plan with 100 webhook calls included.
