[Spce-user] asterisk extension prefixes

[Skyler]

Hello,

 Maybe if I give more info it will help the question.

 What I would like to do is port over an app from our old Asterisk setup
to spce. This would require fancy dialplan mods in asterisk and adding
usr_preferences similar to cfu in csc. I have found how to add the
custom text field in csc/api so far.

 I am looking to find out how _vmu. is hardcoded in spce so when a
number is added into API then 'dfg' is added automatically to the number
entered into my custom csc field, then I can do the similar routing via
usr_preferences in kamailio > asterisk. ie: exten => _dfg.,1,Goto(myapp,
${EXTEN:3})

 Where or how does spce harcode the vmu prefix when adding into
usr_preferences?

Thanks,
Skyler
