Connect with Twilio without using microphone - ios

I use Twilio to deliver audio messages with VOIP, and I don't require any voice input. But By default on the first call the system asks for Microphone access permission.
How to remove this permission accesss, I don't neeed it.
I'm on iOS and using Objective-c.
Thanks !

The Programmable Voice SDK for iOS is intended for two way voice communications and that's why it requires microphone access. I don't think you can achieve this delivery of audio messages without that permission.

Sending voicemail to group of numbers?

I am just exploring voicemail at Twilio, and I thought that I can ask a related question here.
How would I send a voicemail to a group of numbers (as an effort of voice based marketing campaign)? what APIs will I need? and is there any related docs about it?
Shall we send an audio file? Or can we create the voice on Android or iPhone and send it using Android SDK or iPhone SDK?

You can call those numbers and play an audio file using the Play verb. To call a number, you can use our REST API. Here's documentation on how to do that in multiple programming languages.
Hope this helps you out, but come back here if you have any more questions.

Using Twilio for mobile-app to mobile-app voice calling

We have an iPhone app and would like to provide the ability for our users to voice call each other without needing landlines, telephone numbers or use their calling minutes. What is needed with Twilio to do mobile-app to mobile-app voice calls?
Twilio evangelist here.
I'd start by checking out or Twilio Client for iOS quickstart. The short version is you'll need to set up some kind of back end service that can generate tokens and TwiML instructions, then in your iOS app use our iOS SDK to connect to Twilio and make or receive calls.
Hope that helps.
