Wifi calls keep disconnecting!
What is Apple doing about the WiFi call drop issue with the IOS 16.5 update? I have a iPhone X. Never had an issue with WiFi calls until the last update.

Question marked as
Did you contact your Carrier or your ISP?
WiFi Call is a Carrier Specific feature. Contact your Carrier (Cellular Service Provider), the agency that issued the SIM / eSIM to you.
When making WiFi calls, the data packets of the call are routed through an internet service provider (ISP) before reaching the recipient. The ISP acts as an intermediary between your device and the cellular service provider's network. The cellular service provider is the company that provides you with cellular connectivity, while the ISP is the company that provides you with internet connectivity.
If the ISP and the cellular service provider are the same company, there is typically no issue with prioritizing WiFi calls. In such cases, the ISP understands the importance of WiFi calling for the cellular service provider's customers and ensures that the necessary quality of service (QoS) mechanisms are in place to prioritize these calls. QoS ensures that certain types of traffic, such as voice calls, are given priority over other types of traffic on the network.
In summary, when the ISP and the cellular service provider are part of the same company, WiFi calls are typically assigned priority and treated with QoS mechanisms. However, if there is no partnership or disagreement between the ISP and the cellular service provider, WiFi calls may not receive the necessary prioritization, potentially leading to issues with call quality and reliability.
