Re: [Linphone-users] Linphone won't run in background on iOS or announce when calls arrive

Hi Germán,

Thank you for this reply, it is valuable in that it confirms that we can’t use 
Linphone in its current form.

I have also cross posted your response to the 3CX customer forum so that we 
have a record of the answer over there.

Have a good day,
Daniel

Karl,

if you are connecting with Linphone iOS to your own PBX (and not 
linphone.org), you need the PBX to issue push 
notifications. See the following for more information:

https://wiki.linphone.org/xwiki/wiki/public/view/Flexisip/D.%20Specifications/Push%20notifications/

https://wiki.linphone.org/xwiki/wiki/public/view/Lib/Features/Push%20notifications/IOS%20push%20notification%20management/

https://stackoverflow.com/questions/21356290/how-linphone-support-push-notifications-on-android-ios

This also requires your own custom compiled version of the Linphone iOS client 
that will use your own Apple push notification (APNS) credentials. On Android, 
you can use the stock Linphone app from Google Play by activating “background 
mode” (Linphone Settings -> Advanced -> Background mode) - where the app will 
continue to run in the background, and stay connected with the SIP server. That 
feature isn’t available on iOS as Apple is more restrictive with apps running 
in the background.

Cheers, Germán

It seems my problem is exactly the same as Daniel Garner's. iOS 15.6, Linphone 
4.6.5

I've tried all of the following, but nothing has worked:
This is an unlocked iPhone SE. I've reset the phone, uninstalled and 
reinstalled Linphone many times. I checked Background Apps, and Linphone is 
there and enabled. I've cleared the network connections (as recommended by a 
few websites I found). Further, Linphone will not even ring the telephone even 
when it is in the foreground. It only vibrates.  Push is enabled on Linphone.

A technical bit worth noting--On Android, Linphone installs a service that is 
constantly visible and keeps the phone in contact with the Voip service. On 
iOS, though, Linphone does not do this. I read that iOS has limitations that 
prevent that solution, but I have no idea why iOS would be designed that way.

Also, there is extremely little help through Google searches which leads me to 
think this might be a relatively new problem. I can't imagine with over half a 
million users of Linphone that only Daniel Garner and I have been the only ones 
to see it.

If I find a resolution I'll reply to this email.

[Linphone-users] Calls do not announce on iOS with app in background

[Daniel Garner via Linphone-users]

Hello,

I am using an iPhone XR on iOS 15.6 with Linphone 4.6.5, connected to an 
extension hosted in 3CX version 18 Update 4 build 965. I'm using Linphone 
because it supports h264 video from our door entry phones, and the 3CX app only 
supports VP8.

When I have the app open on the screen of my iPhone it works perfectly, but 
when in the background it does not ring. I have push notifications switched on 
in the PBX and in the Linphone app.

Could this be a known issue or is there perhaps some known config that might 
work for this combination?

Thank you,
  Daniel
