Configuring SCTP Support for SIP

RFC 4168, The Stream Control Transfer Protocol (SCTP) as a Transport for the Session Initiation Protocol (SIP), specifies the requirements for SCTP usage as a layer 4 transport for SIP. Use the following steps to:

configure SCTP as the layer 4 transport for a SIP interface
create an SCTP-based SIP port
associate phy-interfaces/network interfaces with SIP realms
identify adjacent SIP servers that are accessible via SCTP
set SCTP timers and counters (optional)
