The present document defines the transport of Inter System Interface (ISI) PDUs using the Session Initiation Protocol (SIP) as transport layer and the Session Description Protocol (SDP) as media control protocol. It specifies:
- SIP methods and header fields used for transport of ISI PDUs; and
- the SDP content; and
- use the ISI Mediation Function which coordinates the communication between TETRA systems.
The ISI Mediation Function specification applies to an IP based TETRA Switching and Management Infrastructure (SwMI) which supports the ISI
