Asterisk的AMI接口已经很丰富了,如果需要扩展,可以参考本文。
一、扩展Asterisk的AMI接口
涉及文件:main/manager.c
1、函数注册
添加 myOriginate接口
在函数int __init_manager(int reload)中添加如下代码:
ast_manager_register_xml("myOriginate", EVENT_FLAG_ORIGINATE,action_myOriginate); // Add by Mike
2、功能实现:
View Code
//Add by Mike static int action_myOriginate(struct mansession *s, const struct message *m) { const char *name = astman_get_header(m, "Channel"); const char *exten = astman_get_header(m, "Exten"); const char *context = astman_get_header(m, "Context"); const char *priority = astman_get_header(m, "Priority"); const char *timeout = astman_get_header(m, "Timeout"); const char *callerid = astman_get_header(m, "CallerID"); char tmp[256]; int i=0; sprintf(tmp,"%ld_%s",time(NULL),name); int tmpLen = strlen(tmp); for(i=0;i<tmpLen;++i) { if(isalnum(tmp[i])) continue; tmp[i]='_'; } char fileName[1024]={0}; sprintf(fileName,"/var/spool/asterisk/outgoing/%s.call",tmp); // FILE *fp = fopen("/var/spool/asterisk/outgoing/1.call","w"); FILE *fp = fopen(fileName,"w"); char buf[1024]={0}; sprintf(tmp,"channel: %s\r\n",name); strcpy(buf,tmp); sprintf(tmp,"Callerid: %s\r\n",callerid); strcat(buf,tmp); strcat(buf,"MaxRetries: 1\r\n"); strcat(buf,"RetryTime: 1\r\n"); // sprintf(tmp,"WaitTime: %s\r\n",timeout); sprintf(tmp,"WaitTime: %s\r\n","30"); strcat(buf,tmp); sprintf(tmp,"Context: %s\r\n",context); strcat(buf,tmp); sprintf(tmp,"Extension: %s\r\n",exten); strcat(buf,tmp); sprintf(tmp,"Extension: %s\r\n",exten); strcat(buf,tmp); fwrite((void*)buf,strlen(buf),1,fp); fclose(fp); return 0; }
二、配置Asterisk
1、编译安装
make && make install
2、添加拨号方案
在文件/etc/asterisk/extension.conf中加入以下代码:
[DLPN_MeetingWithOutRecord]
exten
=>_63XX,1,Answer()
exten
=>_63XX,n,MeetMe(${EXTEN},Mw,1234)
exten
=>_63XX,n,Hangup()
三、AMI调用测试(Python):
View Code
#! /usr/bin/python import socket def strLogin(usr,pwd): msg = "Action: login\r\n" msg += "Events: off\r\n" msg += "UserName: " + usr + "\r\n" msg += "Secret: " + pwd + "\r\n" msg += "\r\n" return msg def strCall(strNum,strCallid): msg = "Action: myOriginate\r\n" msg += "Channel: SIP/"+strNum+"\r\n" msg += "WaitTime: 1\r\n" msg += "CallerId: "+strCallid+"\r\n" msg += "Exten: "+strCallid+"\r\n" msg += "Context: DLPN_MeetingWithOutRecord\r\n" msg += "Priority: 1\r\n" msg += "\r\n" return msg def strLogoff(): return "Action: logoff\r\n\r\n" def strHangUp(strNum): msg = "Action: Hangup\r\n" msg += "Channel: SIP/"+strNum return msg def main(): s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((raw_input("IP : "), 5038)) if not s : print "Connect fail!" return else : print "Connect success!" strNum = raw_input("Input number to dail:") strCallerId = raw_input("Input caller id :") msg = "" msg += strLogin(raw_input("username :"),raw_input("password")) msg += strCall(strNum,strCallerId) msg += strLogoff() s.send(msg) while True: data = s.recv(1024) if not data : break else : print data s.close() if __name__ == '__main__': main() #raw_input("Press Enter to continue")
好,就这些了,希望对你有帮助。
