Platform FAQs
Full multi-tenant support: configure separate SIP trunks, prompts, knowledge bases, and API keys per customer. Isolated logging and analytics per tenant. Dynamic outbound VoIP configuration via API lets you programmatically set telephony settings per customer or campaign.
Never. We maintain 100% backwards compatibility across all API versions. We don't deprecate endpoints or force migrations. Your code written today will work years from now. We respect that you're building production systems on our platform.
If you're looking for a no-code or low-code solution, or you don't have a technical team at your disposal, Dasha may not be the right fit. There are many no-code and low-code voice AI products on the market. Alternatively, contact us and we can connect you with our SaaS partners who are building no-code solutions on top of Dasha.
How to evaluate Dasha for your SaaS
A practical 3-step framework
01
Build one agent end-to-end
SIP number → Dasha agent → your backend API call → response → hangup. This validates the core loop.
02
Load test your target concurrency
Even a small version of your real target. Measure latency, stability, cost/min, failure modes.
03
Test per-customer configuration
Separate SIP trunks, prompts, knowledge bases, logging. Does dynamic outbound config cover your needs?
