After upgrading to SDK version 3.16.0 I am facing initialize error as it misses permissions.
I have manually toggled SDK enableAskingReadPhoneStatePermission() method to true, but it doesn't helped.
Documentation:
https://webex.github.io/webex-android-sdk/v2/com/ciscowebex/androidsdk/phone/Phone.html#enableAskingReadPhoneStatePermission-boolean-
Seems that there is some troubles with permission requester at the SDK layer
