I just realized I said one piece wrong in this. 'gate' is not the context, it is the dynamic feature designator. I can illustrate this better by posting my front gate context.

[front_gate]
exten => <number gate dials goes here>,1,Set(__DYNAMIC_FEATURES=gate)
  same => n,Goto(frontgate_queue,${EXTEN},1)
