How to call a context and return to the main context in asterisk?

问题

Here is my dial plan in asterisk:

[main-context]
exten => s,1,Gosub(subcontext,s,1)
exten => s,n,NoOp(End Main)

[subcontext]
exten => s,1,NoOp(Start subcontext)
exten => s,1,NoOp(End subcontext)

The problem is that when subcontext finishes, execution doesn't return to main-context and exten => s,n,NoOp(End Main) doesn't execute. How can I solve this?

回答1:

As Karadous posted above: a GoSub routine must have a matching Return() application call.

[main-context]
exten => s,1,Gosub(subcontext,s,1)
same => n,NoOp(End Main)

[subcontext]
exten => s,1,NoOp(Start subcontext)
same => n,NoOp(End subcontext)
same => n,Return()
