Linphone for IOS not receiving calls after 5 minutes not using it

[asder78]

I have two linphone acounts

• alfredo_003@sip.linphone.org, in a Windows Linphone, version 5.1.2
• alfredo_002@sip.linphone.org, in an Iphone SE, version 17.1.2; linphone version is 5.1.1, SDK 5.2.106

If iphone screen is on, i can call from Windows client to IOS client correctly, it works great

But, if i don't use iphone at all for (aprox) five minutes, if i call from Windows Client to IOS client the call is not presented on the iphone

May be it is a bug, or may be i have to adjust some settings?

Thanks in advance

Hi Alfredo,

iOS apps can't live while in background. The only way for an app to be waken up is to receive a push notification from an Apple push server.
If you are using our own linphone-iphone app from the App Store you should receive this push. If you don't, please upload debug logs from the app so we can check what happens.

Cheers,

Attached you can find a log file
linphone_log.gz

I made a call from Linphone_Win (alfredo_002@sip.linphone.org) to Linphone_IOS (alfredo_003@sip.linphone.org) at 12:26

Linphone_Win ended the call 50 seconds later (aprox); nothing happened at Linphone_IOS

Linphone_IOS waked up at 12:28 with an empty call

There are no logs at 12:26

Logs in that interval are:

Hi,

the 5.2.0 version of linphone-iphone is arriving on the stores in the coming days, please give it another try with the new version when available. If it still do not work, we will investigate deeper into this issue

[asder78]

I've updated to version 5.2, now available at App Store

I'm, afraid it is still failing

I attach log file, i made a call at 12:08, not ringing until 12:10:50 aprox
linphone_log.txt

It is notorious that there are no messages in log from 12:00:24:060 until 12:10:51:098 (remember a call was made at 12:08)

I would like to add to this that we have the same problem with the Linphone (iPhone) downloaded from the App Store.
We just ran three tests (with logging turned on and sending the logs right after the call). Three scenarios (and results):

1. Linphone not running in foreground: call does not ring device
2. Linphone in foreground (has not been used yet this day): call does not ring device
3. Linphone used to make call, and then right after we send a call to it: call rings as expected
   We're happy to help troubleshoot this in any way that is helpful to you.
