ATCF enabled in two separate realms
Hello,
Hope everybody is doing well. According to configuration guide, in eSRVCC implementation scheme an MSC server should be connected directly to ATCF entity and not via P-CSCF. Does it mean that we need to organize two separate realms and two separate sip-interfaces with enabled atcf feature:
1) first realm/sip-interface for SGi (VoLTE leg) connection
2) second realm/sip-interface for Mw (2G/3G leg) connection
In other words: if ATCF is enabled on two sip-interfaces, will an SBC correlate two INVITEs with a reference to the same STN-SR received on these sip-interfaces?
Thanks and regards,
Daureen
