Hi,
I have gone through the logs (SD-AvayaBBDMasked.txt) and it looks like registration is getting successful and infact App has already consumed OnRegistrationSuccessful() callback.

Regarding your new queries:
1. Call object and related methods are being used for call control. You need to change in the CallType in the CallCreationInfo for HTTP calls. You can find the APIs for
Android:

iOS:

2/3: you can check if you can find "CCallServiceImpl::CreateCall" in the debug logs. Here is where the call is getting created.
Hope this will help!
Thanks,
