About MobileExt Softphone
Cloud-based SIP softphone for secure business communication.
Core Functionality
📞 SIP VoIP Calling
Make and receive crystal-clear voice calls directly through your organization's cloud PBX system. Works over Wi-Fi and mobile data — no desk phone needed.
🔄 Always-On Call Readiness
Never miss a business call. MobileExt stays connected in three states:
App open — full real-time calling
App in background — persistent SIP service keeps registration alive
App closed/terminated — FCM silently wakes the app the moment a call arrives
🔔 Background Service & Notification
A lightweight foreground service runs quietly to maintain your SIP connection. A persistent notification confirms your line is active — standard behavior on Android for all professional calling apps.
📩 Business SMS
Send and receive SMS messages through your cloud extension, keeping all business communication in one place.
☁️ Cloud Extension System
Your mobile becomes your office extension. Calls route through your company's cloud PBX just like a desk phone — same number, same contacts, same call flows.
