If a function is called from many places, use the stack backtrace to determine the specific calling sequence.

如果在许多地方调用了一个函数，可以使用堆栈跟踪检查调用序列。

An IMS call initiated from the SIP client typically triggers a sequence of asynchronous TCAP events between the next-generation application and the TCAP stack interface.

SIP客户机发起的IMS调用通常在下一代应用程序和tcap堆栈接口之间触发一系列异步tcap事件。
