将.so与星号电话集成

Question

I have an application running on an Asterisk telephony server that alters the voice packets of an incoming call. To do this, I have followed the steps:
1. I built an so of the application (coded in C ).
2. Loaded the application onto asterisk.
3. Reloaded the dialplan via dialplan reload
4. The function is registered in asterisk by its name SampleFunc
5. I am calling the function from within the dialplan like so:
exten => 0,n,SampleFunc()

Ideally, I would like the .so to function as long as the call is on. Right now it just goes into the function as soon as the call connects and then gets out and proceeds with the rest of the dialplan. My question:

1. How do I get it to loop while the call is on?
2. Is there anything else that I may have missed?

PS: This may be few details to go with. Short of posting the actual code, please let me know in case more details are needed.

如果您需要在对话和拨号计划进行时更改音频，则可以实现对正在使用的星号音频编解码器进行修补。
