我想用chan_dongle Asterisk模块做Vicidial工作，使用华为的USB调制解调器作为GSM网关（中继/载波）的星号。
在手动模式下，一切正常。
只有将Vicidial Campaign设置为AUTODIAL模式，并且在背景中进行呼叫以及在客户应答之后，才会出现问题，该呼叫应连接到与其代理连接的现场SIP电话会议。
问题是这个电话的本地频道是在接听电话后被挂断而没有连接到会议。 这是每个电话。 在这个代理旁边连接到客户可以和他通话，但是在33秒之后，他放松了通话控制，只有客户可以挂断电话。
在手动模式下，一切工作正常，会议包含2个本地通道（encryption狗拨打电话）和sip（从zoiper到星号的连接）。
我的encryption狗拨号scheme：
