Now my main app is already invoked voip callkit, I would want to invoke voip on iWatch app, but I have some issue: 1、How to deal audio data and network connect of iWatch voip ? can we depends on iPhone app? 2、How to use voip callkit on iWatch that only via bluetooth connect ? 3、If main app is already support voip callkit, how to support callkit for iwatch? Do we need to repeat and independently implement callkit, network, and audio on iWatch? 4、how to add support dial number on iWatch use by the thirdpart app? the case is the same with on the iPhone use, user can send dial by system call record . Any help is appreciated, thanks in advance.
