3. Overview

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

5. Mobicents SS7
● Mobicents SS7 provides most of the SS7 protocol stack

6. 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
