[asterisk-users] Asterisk Realtime Extension... strange behaviour

I encountered a strange behaviour using realtime extensions... (on 
Asterisk 11.2)

when I use the following static dialplan, everything works as expected..:

exten =>  110,1,Dial(DAHDI/g0/${EXTEN})
exten =>  112,1,Dial(DAHDI/g0/${EXTEN})
exten => _XXX,1,Dial(SIP/${EXTEN})
exten => _X.,1,Dial(DAHDI/g0/${EXTEN})

will say... if a sip phone calls "110" or "112" the call is routed into 
PSTN (german emergency call)
if a sip phone calls any three digit number, the call should be routet 
to the corresponding SIP user
and if a sip phone calls any other number the call should be routed into 
PSTN... thats ok and works as expected.

when I change to realtime:
switch => Realtime

and put the diaplan into the database
id    context    exten    priority    app    appdata
"1"    "from-sip"    "110"    "1"    "Dial"    "DAHDI/g0/${EXTEN}"
"2"    "from-sip"    "112"    "1"    "Dial"    "DAHDI/g0/${EXTEN}"
"3"    "from-sip"    "_XXX"    "1"    "Dial"    "SIP/${EXTEN}"
"4"    "from-sip"    "_X."    "1"    "Dial"    "DAHDI/g0/${EXTEN}"

only the emergency calls work and any other call goes to DAHDI... I cant 
reach any other SIP phone.
Even when swapping the content of the rows 3 and 4 in the database to
id    context    exten    priority    app    appdata
"1"    "from-sip"    "110"    "1"    "Dial"    "DAHDI/g0/${EXTEN}"
"2"    "from-sip"    "112"    "1"    "Dial"    "DAHDI/g0/${EXTEN}"
"3"    "from-sip"    "_X."    "1"    "Dial"    "DAHDI/g0/${EXTEN}"
"4"    "from-sip"    "_XXX"    "1"    "Dial"    "SIP/${EXTEN}"

makes no difference...
I thought, using realtime extensions would read the dialplan from top to 
bottom, ordered by "id"... but it
seems to be ignored somehow and the extension "_X." catches the calls 
before the extensionpattern "_XXX" is reached.

I _could_ avoid this be prefixing "external" numbers with a leading 0 
for example... but I dont want to... as I said.. using
static extension via extensions.conf the dialplan works as expected...

Am I missing something?
