Asterisk中实现回拔

在Asterisk1.6中似乎提供一个AMI指令实现回拔功能，就是通过指令让服务器分别拔打两个号码。

 Asterisk.Api.Originate ori = new Asterisk.Api.Originate();
                ori.Account = "30855";
                ori.Channel = "SIP/100036";
                ori.Context = "DLPN_DialPlan1";
                ori.Exten = "1100002";
                ori.Priority = "1";
                ori.CallerID = "";
                ori.Timeout = "30000";
                ori.Send(callback）
