Hi,
I didn't mention in my reply, and it wasn't probably clear, that Kamailio
won't send the actual push to Apple or Google (for GCM).
This needs to be implemented separately, either with a self written service
or using a web service like the Amazon's one.
In the example from my presentation the call to
lua_runstring("do_push([[$hdr(X-VxTo)]], [[$tU]], [[$hdr(XVxFrom)]],
[[$fU]], [[$ci]])")<0)
is actually just an example of where, in the Kamailio script, the logic for
sending the push should be placed.
Regards,
Federico

Hi Benjamin,
if you don't plan to support multiple devices per account just the
t_suspend/t_continue pair should be enough to support push notification.
This being said you can easily integrate the example in my presentation in
the Kamailio's configuration given in the Asterisk/Kamailio integration
page.
For the INVITE you have to modify the route[LOCATION] and, instead of
performing the lookup, suspend the transaction and send the push. In this
way you'll also send the push for every INVITE, regardless of the
registration state. You have then to modify the REGISTRAR route after
calling save() to resume the transaction or to append new branches (if you
use tsilo). I think that the snippets from my example should be enough.
Hope this helps.
Regards,
Federico

Hello, my goal is to address iOS 10's removal
of periodic TCP connections
in iOS apps with their replacement PushKit, a push-based alternative all
VoIP apps should implement.
In order to have iOS apps receive SIP calls in the background, I believe
I need to use tsilo to suspend the INVITE transaction send a push
notification to the device. I have been following the presentation here (
http://www.kamailio.org/events/2015-KamailioWorld/Day2/20-
Federico.Cabiddu-Kamailio-In-A-Mobile-World.pdf) however I am not sure
how to integrate it with Asterisk (http://kb.asipto.com/asterisk
:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb).
My questions can be summarized below:
(1) What changes need to be made from Federico's presentation to use with
the Kamailio/Asterisk integration?
(2) How can I modify the config to send push notifications for EVERY
invite? This is to address the scenario where a device goes offline before
the SIP registration expires and a call is received within that window. iOS
is very aggressive about killing background applications so it's likely as
soon as user leaves the VoIP app, the device will become unreachable.
Thanks for any help.
