使用星号拨号计划进行多次通话

Question

I want to make multiple calls at the same time using using sip dialplan, like :

exten => _X.,1,Dial(SIP/${DIAL}${DIALSTR})

while, in my dial variable there are multiple numbers like and there context is this way:

local/11111111111&local/33333333333&local/5555555555&local/777777777777@scl_local 

I want to call all the numbers at the same time, so I created context above; but that called only one number and got disconnected.

I want to dial something like this:

SIP/11111111111,33333333333,5555555555,777777777777

Answer 2

上面的拨号方案同时拨打所有提及的号码，无论谁先接听电话，都会接听电话，其余的将断开。
