A phone system
built for your industry
Ready-made IVR scenarios and queue structures mean your call flow works from day one.
What our customers
say
“All of our call flows are now in order. We manage branches, departments and queues from one panel; opening a PBX for a new customer takes minutes. Recordings and reports make audits far easier.”
“We run it on our own server (on-premise). Tenant, licence and trunk management sit on one screen; after go-live our ops team dropped to two people.”
“We deliver it white-label under our own brand. Multilingual IVR and the AI assistant give our international customers the same experience.”
Frequently asked
Does it run on our own server or in the cloud?
Both are possible. Install Stella in your own data centre (on-premise) or use the hosted cloud version. The licence and admin panel are identical in both deployments, and a database migration tool is provided for switching.
How does the multi-tenant structure work?
Each customer is created as a separate tenant with its own extensions, queues, recordings and limits. A super admin sees every tenant, trunk and licence from one panel and can log in on behalf of a tenant.
Do you support white-label?
Yes. Panel logo, colour theme, domain and e-mail templates are customised to your brand, so your customers use the system entirely under your own brand.
Can we use our own numbers as a telco or operator?
Yes. SIP trunk definitions are operator-independent; you can define your existing lines, number blocks and emergency-number behaviour (112/155).
Which languages are supported?
The interface runs in Turkish, English, German and Arabic (Arabic right-to-left). IVR prompts and AI assistant scenarios are defined per language, so you can serve international customers in their own language.
Will our existing IP phones keep working?
Any SIP-compatible IP phone, gateway or softphone works. Provisioning configures the devices automatically straight out of the box.
