Re: [Linphone-developers] UDP background calls on iOS 4.3+

[Rene Dohmen]

Jehan,

Thanks again for the answer.
I've sended a support request to apple myself, with the logs and some code stuff.

I updated one of my phones to iOS 4.3.1 ; and I noticed one weird side effect; when the app is in background mode, nothing happens when I try to call it.

When I call twice and then (after the 2nd call) swith the app to foreground mode; I receive an incoming call
See the attached log file...


Kind Regards 

Rene

Hi Rene,

I  agree most of the current SIP providers are UDP only. My opinion for iPhone is that, if you don't want to dramatically reduce autonomy UDP is not an option.

Anyway regarding the UDP support in Linphone, there is 3 posibilities: Either it's a bug in Linphone's usage of UDP voip socket or it is a bug in IOS 4.3 or it is a decision from Apple to no longer authorize UDP voip socket.

Before investing a lot of efforts in trying to fix this problem, I want to make sure this is not option 2 or 3.

I'll post a question regarding this point on the apple forum.

Cheers

Hi,

i'm still wondering if the new linphone iphone app will support  background UDP again with iOS 4.3+

Are you gonna wait until apple fixes their (??) problem?

I used linphone git version to build a rebranded app for the dutch market, and so far I love the project and it's code. I now have an unreleasable app due to the UDP background support not working anymore in iOS 4.3. The only answer i got from you guys, so far, is that theoretically nobody uses UDP voip and that you don't think it's a priority; Still nobody in NL with an voip account can use your app, other people on the list report the same problem. So I think it's a rather practical one. 

I know that there is no real support on GPL apps, but i would like to know if the problem will be addressed or not. 

I'm absolutely willing to do some extra  coding myself, but the whole network programming stuff, especially on iphone, is new to me. If I can help with anything at all let me know. If you want a NL SIP account to see that TCP won't work just ask. 

Kind Regards,

Rene Dohmen
