[asterisk-users] i extension not triggering

[Mitch Claborn]

Asterisk 1.8.10.1~dfsg-1ubuntu1
See dial plan code below.  When I dial 123 from a phone in this context, 
I simply get a busy signal. Why doesn't the "i" extension get 
triggered?  Console at verbosity of 10 only shows "  == Using SIP RTP 
CoS mark 5".

[DockPhone]
exten =>288,1,NoOp(Dock Phone)
   same =>n,Dial(${DOCK_RECIPIENTS},30,kt)
include =>emergency-services

; the 'i' is not triggering, not sure why
exten =>i,1,NoOp(invalid extension from dock phone i)
   same =>n,Playback(custom/dock-invalid)
   same =>n,Hangup()
exten =>h,1,NoOp(hangup extension from dock phone)
   same =>n,Hangup()
