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];

Could you please provide client logs or call stack to investigate the crash.

btw, you can check documentation how to configure SIP server:
https://www.devconnectprogram.com/site/global/products_resources/avaya_client_sdk/programming_docs/current/macos/communication/tech/initializing_sdk.gsp

The code is also available in the sample app, so you can find the difference.

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