Voip or voice call record - Xamarin.forms

I am trying to develop a xamarin.forms app which have the functionality to make call and record it.Why I am writing this question is I want some clarifications regarding this.I cant find a proper solution on web.
1 The app workflow will be like this. When user tap on the number on my app it will open the dialer (in Android and iOS). User will complete the call and return back to app.The app will get the call record and store it.
Is this scenario possible with Xamarin.forms? If possible, any links will be appreciated.
2. Suppose the above scenaerio is not possible, then what will be the best approach? I heard about Twilio voip call sdk for xamarin. Is Twilio really support voip call for xamarin? I found these links, but it seems outdated.

https://www.twilio.com/blog/2014/10/twilio-client-for-xamarin-part-2-ios.html Is there any other voip sdk available which will fullfil my requirement.Any help is appreciated. Because I have been stuck on this for days.
EDIT If I implement Twilio calling in web and calling it as a webview in mobile.Can I make work above scenario?

Is it possible to implement dynamic notifications on Apple Watch without a launchable app?

I've designed a custom notification for an app I'm working on for Apple Watch. The notifications look good but because of the current technical limitations I don't want to build a launchable app or glance until I have mic and speaker access. Is it possible to display dynamic notifications without having an app icon on the home screen of the watch or is the watch app mandatory to have a dynamic notification at all?
No, you will need to add a dynamic Notification scene in your Watch app.
If you want to read more information about this I'd refer you to this page:

Is it possible to get an app to open up when entering a beacon region / within range of a beacon/ibeacon

I'm exploring the end user experience for a beacon prototype but I'm struggling to find any end-user scenarios that involve the app becoming active / opening up on the screen when within range.
I can get the app to send a notification and this is the most likely experience on both Android and iOS but does anyone know if it is possible to get the app to open up?
It's unlikely that I'd want real customers to have their experience interfered with in this way, I think it's ok if the app is already running and is open but not if it's running but not open.
Thanks
On Android this is possible. The reference app for the Android Beacon Library demonstrates how to do exactly this.
On iOS, it is not possible due to OS security restrictions. See here for details. The best you can do is send a local notification to the user when the beacon is detected, then if the user gestures to it, bring up the app.

How can I run chromecast sample without whitelisting

When I try to write my custom app, I am asked to white list the device. But how can I run the sample apps without whitelisting my chromecast device.
Sample apps here, https://github.com/googlecast/CastHelloText-android
First you need to add the app on your Google Cast SDK Developer Console. Once it is added, click on your application and publish the app. As stated:
When published, your application can be launched on any device. When
unpublished, your application can only be launched on your authorized
devices.
If you want to use your own receiver, you have no choice but to whitelist your device for your app (unless you decide to publish your app which is not a good idea). You can use the app id that is provided in that project and that refers to a published on but that is not your receiver anymore.

Question of XCode app development: How to create a dial pad for phone call?

Currently I am working on phone call app on iPhone but can't find a reusable UI for the dial pad as the one built-in on iPhone. It's dirty to layout the UI and sound for each and I would like to know does anyone have such experience?
Thanks in advance.
