SLTVoice

SLTVoice is a SIP phone/VoIP extension built for SLT Megaline, SLT Fiber, and SLT 4G LTE customers. It can be used alongside SLT landlines, allowing you to connect up to four smart devices to a single allocated SLT landline, enabling seamless voice calls across devices.

Note: The app is exclusive to SLT Megaline and SLT Broadband customers. To use it, you must have a VoIP account created under your phone account, and the app will operate only within the SLT Broadband network (for example on SLT Home Wi‑Fi).
