Hi there, I'm using pjsua2 API on Android, and I want to send a final response to a Request(for example INFO) in onCallTsxState(), but I can't find any method like 'sendResponse'. Is there any method I can call or I should code it myself? thank you guys! -------------- next part -------------- An HTML attachment was scrubbed...
