[Linphone-developers] linphone ios9

Hi All, I'm using Linphone for iOS devices with SIP over TCP.
So far, there's no problem and it works well, I mean till iOS 8.4.x

Right now I'd to support new iOS9 but reading the new iOS 9 API, I saw that setKeepAliveTimeout:handler: has been deprecated.
Up to now, as far as I know, this was the only way that a VoIP SIP app on iOS could maintain its registration with the SIP-server.

Please try to image a scenario in which the app is in the local LAN without Internet connection, there's no way to refresh the SIP register stored into SIP server hence the app cannot be woken up anymore.
I think even if you have an Internet connection, the app won't able to refresh its register to the SIP proxy, and I'm wondering how the SIP proxy can forward the INVITE to the app? 

This technique is used by various apps like your Linphone and others.....
Apple says to use The UIRemoteNotificationTypeVoIP, but in my opinion it's not useful....due to wake-up time, and so on...
I'm wondering what you are going to do and how can we solve this issue?
Would you mind share your opinion with me, please?

Thanks in advance
