linphone-iphone in background-mod 打不通电话？

Question

我在 iOS 应用程序中使用 linphone SDK。

当应用程序进入后台模式时，应用程序有时可以收到来电或推送通知消息，有时则不能。

或者，如果应用在几分钟前处于后台模式，则无法接听来电。

请帮帮我。

我使用 ipad 调用处于后台模式的 iPhone。

ipad的日志：

当我让phone到前台就可以拨号了。

iOS后台模式的APP可能会挂起。您可以使用 PushKit，在向 APP 拨打 VoIP 电话之前向 APP 发送通知。关于PushKit你可以访问https://developer.apple.com/documentation/pushkit 祝你好运！
