ETSI TS 129 231 describes the protocols to be used when SIP-I is optionally used as call control protocol in a
3GPP CS core network on Nc interface, see 3GPP TS 23.231 [1]. The SIP-I protocol operates between (G)MSC servers.
The SIP-I architecture consists of a number of protocols. The following types of protocols are described: call control
protocol, resource control protocols and user plane protocol for this architecture. The architecture complies with the
requirements imposed by 3GPP TS 23.231 [1] and TS 23.153 [2].
Interworking of SIP-I on Nc to external networks is described by TS 29.235 [3].
