New Behavior: In the new Output, a “Discovery Mode” field specifies the method of discovery followed by the actual
P-CSCF Address Information. Also, the new Output displays both IPv4 and IPv6 address information as per
applicability. The new Output remains persistent across ICSR/Session Recovery for all P-CSCF discovery modes.
Additionally, the new behavior maintains the P-CSCF information persistency across inter technology handoffs (like
LTE -> eHRPD, s2bGTP -> eHRPD, eHRPD -> LTE, eHRPD -> s2bGTP, etc.)

CSCuq06604 - PGW does not initiate dns query to resolve p-cscf addr after
epdg-ehrpd ho
Feature Changes
P-GW Did Not Initiate DNS Query to Resolve P-CSCF Address after ePDG-eHRPD Handoff
Previously, P-CSCF address resolution during ePDG to eHRPD Handoff was not supported.
Added support to resolve P-CSCF Address during s2b to eHRPD Handoff if it is not resolved earlier as part of the
ePDG call setup.
ePDG call setup.
Important:
P-CSCF address resolution during Handoff only occurs if it was not resolved in the initial
call setup.
