PJSIP - Incoming Call in Background

[MatthewD]

Has anyone successfully been able to have a local notification be pushed for an incoming call with PJSIP?

I am having an issue that the network traffic seems to be blocked until the keep-alive timeout handler is called or when the app enters the foreground.

So, it takes about 10 minutes before I see the incoming call push notification.

I searched around and saw that people had this issue with the simulator.

I am using both an iPhone and an iPad running iOS 4.3.2. I have not yet tried it on the simulator.

Thanks for any suggestions!

there aren't warranty about instant delivery of remote push notification....

I think you may have misunderstood me.

I am watching the debugger console and seeing if I get any network traffic while the app is running in the background.

I do not get any network traffic until the keep-alive timeout handler is invoked, or if the app enters the foreground.

I think this may be because there is either no TCP traffic when I have an incoming call (I need to try and Wireshark, I suppose), or the TCP socket is set up incorrectly in the PJSIP library, or I am doing something to break the PJSIP library.


EDIT: I think I found my issue. I do not believe the SIP server I am using supports TCP, and TCP is required.

If there is anyone familiar with this library or someone with knowledge of SIP and VoIP, your input will be very insightful.

Hi,

Did u find solution for this ? I am doing same and every time i have to send command 'm' to make call and other side command 'a' to answer the call. Then only call establish. Is there a way so that i can receive call incoming notification on receiver side ? currently i am not getting any notification.

If you have any sample available that will be great help.

Thanks,
Gagan
