Hi Stas,
1. See there, at the end "Voip sockets" 2. Nothing is documented. Apple has never stated that is was supported for UDP in any version. But it apparently worked in some version of 4.x OS before being removed.
3. From our experience we have not been aware of any cases where the TCP nat timeout was so short. If it really exists I don't see any other solution and even how the iOS push notifications could work.
Regards,
Simon

Did I understand correctly that this feature had been disabled in 4.3 and up? Any pointers on docs very appreciated3. IMHO firewalls are keeping TCP ports open for about 5 min or less, so even if TCP SIP enabled it will not work reliably . Am I wrong.

Sent from my iPadOk, thanks.
However, I can’t find a reason why Apple disabled this feature since 4.3+ L

Hi,
The only way to workaround this UDP problem is to force the iphone to stay live by creating a long running background task.
The result is that the device never suspends, which drains the battery very fast.
We don't plan to implement this.
Instead we recommend the use of a TCP/UDP SIP gateway, like our flexisip server running on sip.linphone.org .
Anybody can configure its linphone android or iphone to go through sip.linphone.org to use TCP instead of UDP.
It is rather simple:
domain: your voip provider domain
server: sip.linphone.org
Outbound proxy: yes
Transport: TCP
There is no need to create a SIP account on linphone.org to benefit from this feature.
Regards,
Simon

And how did Bria’s and Acrobits’ developers succeed instead ?

Hi,
From Apple's documentations, there is no trace of UDP support for voip socket at all. It used to work from IOS IOS 4.0 to 4.2, but from my understanding, it has never been officially supported by Apple.
Cheers

Hi Jehan,
is there an official documentation by Apple which states that?

Hi,
It seams UDP background mode is no longer supported in IOS > 4.2. There is no obvious solution except using SIP TCP instead of UDP.
Cheers

Sorry,
That Swedish comment was intended as a comment directly to Ludvig that happened to go to the list.
It merely meant: Good, and good that there are others who have reported the same problem.

Hi all,
I ran into the very same problem myself. This functionality appears to be broken in the Linphone app 1.0.6 present on the App store. No notifications show from incoming calls when, for instance, the home screen is visible. I have only tested the app on IOS 4.3.X
Does anyone know what might have caused this?
Regards,Ludvig Davidsson

Hi all,
seems the function not worked from "iOS 4.3+"
ref : 3/31 "It seems that background incoming calls don't work
any more, transport=UDP, backgroundMode=enabled."
anyone have info about iOS or Linphone update ?
With Regards,
Rex
