M5T SCE SDK for Mobile

In a fast-moving mobile communication world, the M5T SCE SDK for Mobile handles interoperable SIP Signaling and comprehensive Media Management. Mobile SIP Client Engine SDK allows technology developers to bring quick time-to-market SIP-based solutions. Both Over-the-Top (OTT) application developers and OEM manufacturers would benefit from the M5T reliable know-how and integration experience.

Single Portable Code Base

The Mobile SDK offers a single multi-platform and multi-OS code base that can be deployed in any application. It supports Windows, Windows Mobile, Linux, Mac OS, iPhone®/iOS, and Android operating systems. It also supports Intel, PPC, MIPS, and ARM-based platforms. This portable SDK increases developer productivity by providing a universal and multi-platform SIP implementation.


The modular architecture of the Mobile SDK allows for customisation to be added on top of the standard SCE SDK. The available comprehensive API documentation ensures the required extensibility to meet OTT developer and OEM manufacturers specific needs in a fast and easy way. Additional options can also be licensed to speed-up your development.
