Hello, A) SIP-I have the body SDP and plus the body ISUP. ( IAM---> trunk- TDM ---> MGC ----invite/sdp/iam --> MGC ---> TDM --- trunk --- IAM ( I am here again))
INVITE/SDP/IAM SIP-T For ISUP-SIP Interconnections or SIP-I are similar : " SIP-I and SIP-T refer to two very similar approaches for interworking ISUP networks with SIP networks. In particular, they provide the means for conveying ISUP-specific parameters through a SIP network so that calls that originate and terminate on the ISUP network can transit a SIP network with no loss of information. SIP-T was developed by the IETF - the same body that developed the SIP protocol itself - around the same time the most recent version of SIP was being developed (mid-2002). It is defined by RFC 3372, RFC 3398, RFC 3578, and RFC 3204. SIP-I was developed by the ITU in 2004, and made use of most of the constructs defined in the IETF SIP-T effort. It is defined by ITU-T Q.1912.5. SIP-I and SIP-T both define the mapping of messages, parameters, and error codes between SIP and ISUP. Both of them are fully interoperable with compliant SIP network components on the SIP network.
