143 works fine with no segfaults, but breaks something at my end...

ast_data is configured for Voicemail _only_, phones and dialplans are kept in their respective files.

I have configured two voicemail contexts with similar numbers SIP/100 = 100 at internal and SIP/1100 = 100 at external and running everything from .conf files, "exten => _80,1,VoicemailMain(${CALLERIDNUM})" is able to figure out my voicemail context and will only prompt me for the password.

Moving voicemail.conf into the database something breaks, I now have to change my dialplan to exten => _80,1,VoicemailMain(${CALLERIDNUM}@internal) in order to check my voicemail, this will fail for 100 at external so 100 at external will need a similar dialplan with a different context. If I leave it as it is it assumes context=default and fails regardless of anything.

Also, leaving voicemails becomes a problem, below is my macro for placing internal calls..

[Internals]
exten => 100,1,Macro(stdexten,100,SIP/100)

[macro-stdexten]
;
; ${ARG1} - Extension
; ${ARG2} - Device(s) to ring
;
exten => s,1,DBget(temp=DND/${ARG1})            ; Get DND key
exten => s,102,Goto(s,3)                        ; DND key is NOT set
exten => s,2,Goto(s,11)                         ; DND key is set
exten => s,3,ChanisAvail(${ARG2})               ; Is channel up?
exten => s,104,Goto(s,13)                       ; Channel in NOT up
exten => s,4,DBget(temp=CFIM/${ARG1})           ; Get CFIM key
exten => s,105,Goto(s,6)                        ; CFIM key is NOT set
exten => s,5,Dial(Local/${temp}@Internals)      ; Unconditional forward
exten => s,6,Dial(${ARG2},20,tm)                ; Ring the interface
exten => s,107,Goto(s,9)                        ; B party is BUSY
exten => s,7,DBget(temp=CFBS/${ARG1})           ; Get CFBS key

exten => s,8,Dial(Local/${temp}@Internals)      ; Unavailable forward
exten => s,9,DBget(temp=CFBS/${ARG1})           ; Get CFBS key
exten => s,110,Goto(s,11)                       ; CFBS key is NOT set
exten => s,10,Dial(Local/${temp}@Internals)     ; Busy forward
exten => s,11,Voicemail(b${ARG1})               ; Send to voicemail w/ busy announce
exten => s,12,Hangup()                          ; Hangup
exten => s,13,Voicemail(u${ARG1})               ; Send to voicemail w/ unavail announce
exten => s,14,Hangup()                          ; Hangup

Phone number 100 (line-1, vm=100 at internal) calling 100 (line-2, vm=100 at internal) and eventually going to voicemail.

If I change the context of that particular entry in the database to "default" it works...
Somehow ast_data do not resolve the voicemail context of the called party the same way as core asterisk.
The question is; is this intentional or ??

I can resolve the problem by altering macro-stdext to include a third parameter, the voicemail context but that only means additional administration when creating new clients.

[Internals]
exten => 100,1,Macro(stdexten,100,SIP/100,internal)

and 

[macro-stdexten]
;
; ${ARG1} - Extension
; ${ARG2} - Device(s) to ring
; ${ARG3} - VoiceMail context
;
exten => s,1,DBget(temp=DND/${ARG1})            ; Get DND key
...
...
exten => s,10,Dial(Local/${temp}@Internals)     ; Busy forward
exten => s,11,Voicemail(b${ARG1}@${ARG3})               ; Send to voicemail w/ busy announce
exten => s,12,Hangup()                          ; Hangup
exten => s,13,Voicemail(u${ARG1}@${ARG3})               ; Send to voicemail w/ unavail announce
exten => s,14,Hangup()                          ; Hangup

Suggestion ??
