I'm going to jump in here and suggest there _is_ something rather
funcky going on with the "h" extension. I'm using:

[from-sip]
include => local-extns
include => local-calls
include => bus-dialing  ; 9 plus anything outbound
include => misc-extns
include => outgoing-calls
include => parkedcalls
include => zaptel700
include => livevoip-ld
include => special-3digit
include => no-match
exten => h,1,Hangup


; This section for 311, 411, 511, 911, etc.           
[special-3digit]                                      
exten => _X11,1,Dial(Zap/3/${EXTEN})                  
exten => _X11,2,Congestion

; This section is the Last and handles 'no valid extension'
[no-match]
exten => _.,1,Answer
exten => _.,2,Playback(invalid,skip)
exten => _.,3,Hangup

If I dial x3123 (which is undefined anywhere in the dialplan), the
"no-match" section does execute. However, without both the
exten=>_.,3,Hangup AND exten=>h,1,Hangup I'll get the invalid
message played back twice.

If I leave off the exten=>_.,3,Hangup, the sip phone remains
connected (no hangup).

If I leave off the exten=>h,1,Hangup, I get two invalid messages.

So, there is something weird about the "h" stuff.
