If the App running in background with click Home button. This App properly be killed by iOS system. In this situation the CSDK will not receive a call alerting. But this is bad UE. Does any solution with this situation?

Hello willlain

Thank you for your question. Current CSK release is already have a background support.
Application will not be killed by iOS and incoming call could be accepted.

Best regards,
Dmitry

But if I kill the app by double tap home button and swipe the app or my cellphone restart. The CSDK can not receive the new call message, It is that correct ?

PS?The CSDK release note say not support iOS10 not use iOS10 feature. It is that means in CSDK App can not use iOS10 feature? For example CallKit etc ?

If the app is killed or not running any incoming call could be routed to a voice mail (depends on extenstion configuration). When you start application a new voice message will arrive. You can call your voice mail and listen a message and re-call if needed.

About iOS 10 support:
The iOS Client SDK is built using the iOS 9 platform libraries, and the iOS 9 platform libraries are supported on iOS 10. Using the iOS Client SDK with iOS 10 features (Call Kit, Push Kit) is unsupported.
