Example of an access transfer INVITE (SRVCC)
Hello,
Colleagues, who have an experience of VoLTE implementation, could you please share an example of an access transfer INVITE (from MSC to ATCF) which is sent when Calling party makes a handover from VoLTE to 2G/3G ? This scenario is described in A.6.2 of TS24.237.
This INVITE must be forwarded to the I-CSCF or SCC AS, depending on confgiration. In my case ATCF rejects it with 404. According to logs it even does not try to go to local-policy (i added local-policy just for test).
Regards,
Daureen
