VoIP Push notification not work in background and terminate state.

[ritesh5553]

Hello,

We have performed chatting, audio, video call functionality in our project. we got text message related notification, but we haven't got VoIP notification for audio/video call once the app goes in background and terminate the state. we have used the latest framework for audio/video calls. and also sometimes not subscription not work. So can you guide us to complete this functionality?

Thanks.

Hello @Navya-ios ,

I have found some way to solve this issue. You can try as below,

-> Have you added PKPushRegistryDelegate method in appdelegate file? and PKPushRegistryDelegate is only in appdelegate file. otherwise you added more than 1 PKPushRegistryDelegate, it will not work.

-> If you will fail to report 2-3 notification, then Apple will block your notification. so you have to first delete your app then reinstall app.

-> If you have added “answerTimeInterval” in didReceiveIncomingPushWith method. then comment it. you must have to incoming call whenever receive VoIP notification.

Yes PKPushRegistryDelegate methods are in App delegate only, subscription is getting success but incoming call was coming.

Can you please tell me the step by step procedure to work for background call?

[riteshpatel0]

@Navya-ios

How many places to call below method, func pushRegistry(_ registry: PKPushRegistry, didUpdate pushCredentials: PKPushCredentials, for type: PKPushType)

didReceiveIncomingPushWith method is call when your app is in foreground? if not, then first delete the app the reinstall the app.

and didReceiveIncomingPushWith method is call when your app is in foreground? this method is not calling in foreground

[riteshpatel0]

Please try to delete the app and reinstall the app. then check it. if this method is not called then your notification is blocked by apple due to not reporting incoming call.

@riteshpatel0 @ritesh5553 @soulfly @dgem

For voIP notification (for call) In admin panel, I am able to get success in subscriptions but not i am not able to get in queue and not receiving any incoming call when app is in background.

[riteshpatel0]

@Navya-ios

While you are going to subscribe, did you check QBChat service is connected or not?. If QBChat service is not connected then the subscription will not show in the admin panel. and where you are added PKPushRegistryDelegate. if you are not added in appdelegate then VoIP will not work in background and terminate.

[Navya-ios]

@riteshpatel0

We are disconnecting chat service when app goes to background state so, in that case we are not getting video call in background And if we don't disconnect chat service in didEnterBackground we are not getting messages when app is in background

How to overcome this issue?

[riteshpatel0]

@Navya-ios

Can you share VoIP Call functionality related files?

Hello,

This is Nikolay from QuickBlox support.

Please let me know if the issue is still relevant.

Also, please update the SDK to the latest version: https://github.com/QuickBlox/quickblox-ios-sdk/releases/tag/2.17.10

Additionally, please check our new samples: https://docs.quickblox.com/docs/code-samples#video-calling-samples

[vitalyiegorov]

@muteKey Could you please describe how offline call push notification should work? According to the docs it is not clear who should send this notification(voip)? Is this done on QB backend or each client implementation should send it?
