Overview

SS7 Protocol

● Signalling System No. 7 (SS7) is set of signalling protocols 

Mobicents SS7

● Mobicents SS7 provides most of the SS7 protocol stack 

Architecture

● All stacks are simple POJO's● Start-up in any container or as standalone● In Mobicents SLEE Container, SCCP is started as JNDI

Service and MAP RA, ISUP RA looks-up SCCP
