P-CSCF address is empty or null during handover between volte and vowifi
During handover between VoLTE to VoWiFi, P-CSCF address is received as empty from network during tunnel establishment.
What should be the behaviour of UE (user equipment) when P-CSCF address is empty ?
Does UE has to continue with the P-CSCF address received during initial registration ?
Please share if there is reference document for this behaviour.
