SIP->SIP-I interworking
Hello everybody,
I need to configure SIP to SIP-I interworking. I know how to do that except: how the SBC figures out the ISUP parameters, for instance which CIC to use? Do all outbound INVITEs contain the same CIC? Should I modify using HMRs? If all CICs are the same... what the far end softswitch should do? Ignore it? It doesnt need it as it must use RTP IP and port instead to receive RTP media from my SBC.
I wander if there is a RFC or some ITUT document specifying this... Does anybody know?
Thank you,
Petr
