Correct way to revert back to originating server?

问题

I have two servers on the same network. SIP is setup with canreinvite=yes

I call Server 2 from server 1 with DIAL() cmd

What is the correct way to revert back to server 1 after I am complete with the call on server 2 without dropping the channel? (I still want the channel active to offer the user specific options back on server 1).

回答1:

Please use "g" option of Dial command like this:

exten => _X.,n,Dial(SIP/mytrunk/${EXTEN},,g)

After Dial command it will continue to run next Dialplan command of Server 1. More details you can find here:
