M5T SCE SDK for Gateways

The M5T SCE SDK for Gateways allows System Integrators, OEMs, and ODMs to enable voice applications on phone gateways such as IP-PBX, ATAs, digital phone adapters, routers, modems, etc. With a design based on the Intel GRX family, Marvel Armada, and DSP Group Processors/System on a Chip (SoC), the M5T SCE SDK is highly interoperable with any SIP/IMS UA, Proxies, and other types of Servers.

Its provisioning system counts on advanced features as TR.104 model to voice encoding and registration to call control, allowing easy customisation to create a product that meets TTM requirements and specifications.

IETF, IMS, RCS, VoLTE, and PacketCable

The SCE is deployed in a wide range of networking scenarios, whether it is for custom-based, IETF-based, or IMS-based telecommunication networks. The SCE offers many run-time and compile-time configuration parameters that allow your solutions to be deployed in any SIP based environment.


The modular architecture of the IP-Phone and Gateway SDKs allows for customisation to be added on top of the standard SCE SDK. The available comprehensive API documentation ensures the required extensibility to meet System Integrators and OEM/ODMs specific needs in a fast and easy way. Additional options can also be licensed to speed-up your development.
