A flexible solution for handling WiFi to cellular (W2C) handover (e.g., for voice over WiFi (VoWiFi) or video calls) includes: determining, for a wireless network, at least one live conversation performance indicator; based on the at least one live conversation performance indicator, determining at least one W2C handover parameter of a set of W2C handover parameters, the set of W2C handover parameters including a first W2C handover parameter indicating a first trigger condition and a second W2C handover parameter indicating a second trigger condition; and transmitting, by the wireless network, to a user equipment (UE), the at least one W2C handover parameter. In some examples, the W2C handover parameters include a reference signal receive power (RSRP) threshold and/or a received signal strength indication (RSSI) threshold. In some examples, live conversation performance indicators may include a cellular call drop rate, a WiFi call drop rate, and a handover failure rate.
