Siprix with callkit

[babayanta1994]

Please can you create a branch in gitlab with an example with callkit.

[babayanta1994]

we need to open the fullscreen call when a push notification comes in. We need only mini example with worked pushkit integration. Please help

[siprix]

Here is detailed explanation:
https://docs.siprix-voip.com/rst/ioscallkit.html

Also could be usable this one:

[babayanta1994]

Can you make an example that only works through callkit?

[siprix]

Published example app has all required code, listed in manual.
You can use it as is or just copy accouns_model_app.dart, calls_model_app.dart to the own app.
Steps which needs to be done:
a. add push support and create certificates, as explained in the second link in my previous post;

b. run app, add account and get push token
see siprix_voip_sdk\example\lib\accouns_model_app.dart:16

c. for test purposes send push notification using script from paragraph #4
here https://docs.siprix-voip.com/rst/ioscallkit.html#integrate-pushkit-callkit-into-flutter-application

curl -v \
-d '{"aps":{"alert":"test","callerId":"someCallerId1", "pushHint":"somehint"}}' \
-H "apns-push-type: voip" \
-H "apns-priority: 10" \
--cert-type P12 --cert Certificates.p12 \
--http2 \
https://api.sandbox.push.apple.com/3/device/1695d5bf01...e6608

where: Certificates.p12 - path and name of the cert file, configured on step [a], 1695d5bf01...e6608 - actual device token, got on step [b].

=> if everything done properly you'll see incoming call screen triggered by push

d. Add own code or temporary comment lines 66,67 in example\lib\calls_model_app.dart. This code matches SIP and push. When commented it allows to test incoming SIP call without adding any special data to SIP on server side.

---

Simple test case (without SIP server changes):

• run app (move to background or even close)
• send push using script => incoming call screen will appear, you can even try to accept it
• receive SIP call =>call established, sound started

Can you give instruction for callkit without provider? I looked at the instructions and as I understood it is implemented on the basis of CallsModel which in turn works with the provider. How to use it without the provider?

[siprix]

It doesn't require to use Provider.
Just copy accouns_model_app.dart and calls_model_app.dart from example app to the own app and create global instances of these classes: AppCallsModel, AppAccountsModel. In constructor they will subscribe receiving library events.

One more option - create own class which covers required functionality and invoke in its implementation:

    SiprixVoipSdk().callListener = CallStateListener(
      playerStateChanged: onPlayerStateChanged,
      proceeding : onProceeding,
      incoming : onIncomingSip,    //<---
      incomingPush : onIncomingPush,  //<---
      acceptNotif: onAcceptNotif,
      connected : onConnected,
      terminated : onTerminated,
      transferred : onTransferred,
      redirected : onRedirected,
      dtmfReceived : onDtmfReceived,
      switched : onSwitched,
      held : onHeld
    );

It will give you ability to handle all events.
Don't forget to implement code, which put device token to the account properties (see AppAccountsModel::addAccount)
