Introduction to SMG-SS7 Konrad Hammel Sangoma Technologies

SMG-SS7 Asterisk Architecture Wanpipe/TDM Voice API Ss7boxd Ss7boost Sangoma Media Gateway Chan_Woomera Outline 2

SMG-SS7 Architecture 3

Wanpipe –Hardware drivers that control data flow from hardware to kernel space TDM Voice API –Sangoma’s API that allows user space access to voice channels XMTP2 API –Open source kernel space API that controls the flow of MTP2 messages Wanpipe/TDM Voice API/XMTP2 API 4

SS7Boxd and SS7boost SS7boxd Daemon that controls the XMTP2 API Configures and Controls the SS7 signaling links Establishes MTP2 and MTP3 Connections SS7Boost Daemon that handles ISUP Aware of Voice CICs and their location Handles call SS7 call generation and reception 5

Go between SS7 and soft-switch Controls flow of voice channels Handles DSP functions Communicates to SS7boost through the “Boost” protocol Communicates to soft-switch via an Woomera Server Sangoma Media Gateway 6

Asterisk Channel driver (Woomera Client) Uses TCP ports for signaling and UDP ports for audio Very simple Text based protocol Audio is encoded in U-law or A-law Forwards and Backwards Compatible Load balancing and distributed computing Chan_Woomera 7
