I get it. thank you! But I still have a question. Why did not I respond when I started registering a server? That is, there is no success nor failure.

When registering the server, the console kept printing "OM Collection Timer", there is no failure tips. The following is a print log, what is the reason? Is it in connection? Why can not connect? Please answer my doubts, thank you!

Thank you for your reply, I think I have already solved it. I do not know why the "App Sandbox" switch in Xcode "Capabilities" is turned on, and the application does not crash after I close it.

Hello, the program crashed when I called [user start] to start the registration service. The following is a crash message. Please help me to see, thank you.

Thanks, I think I have solved it. It seems that I did not add AvayaClientServices.framework in Embedded Binaries. I can run after added.

Hello, I crashed while creating the client. Seems to be the collapse of CSSignalingServer object nil. Please help me to see, thank you!

CSSignalingServer *SignalingServer1 = [CSSignalingServer serverWithTransportType: transportType hostName: [self sipProxyAddress] port: (NSUInteger)[self sipProxyPort] failbackPolicy:CSFailbackPolicyAutomatic];
