[asterisk-users] If would possible use a custom function in Asterisk Dialplan

[Danny Nicholas]

You could do it as a function if you are C literate.  The simpler way would
be to do it as an AGI where you passed the ${EXTEN} value to the AGI and had
the AGI pass the modified number back as a dialplan variable.

Subject: [asterisk-users] If would possible use a custom function in
Asterisk Dialplan

Hello,

If would be possible to use a "function concept" in side of Asterisk
DialPlan 

For example:

I have following logic in my dial plan remove country code a add an "0"
before the rest of the numbers 


exten => _X.,1, NoOp( call ID ${CALLERID(num)}  exten: ${EXTEN})) ; remove
my country code exten => _X.,n,
GotoIf($["${CALLERID(num):0:4}"="${country-code}"]?international-format:nati
onal-format)
exten => _X.,n(international-format), Set(CALLERID(num)=0${CALLERID(num):4})
exten => _X.,n(national-format), NoOp(call ID: ${CALLERID(num)} exten:
${EXTEN}))

Do you think if would be possible that I could write a function something
like "REMOVEMYCOUNTRYCODE(${NUM})" with a return value of a number with out
country code and with an "0" add in front of the rest of the numbers.

like 

exten => _X.,1, NoOp( call ID ${CALLERID(num)}  exten: ${EXTEN})) ; remove
my county code exten => _X.n,
Set(CALLERID(num=REMOVEMYCOUNTRYCODE(${CALLERID(num)} )); 

then I have to define this function in someway ..

I am trying to googling for a while but I did not find any idea to achieve
this task. 

I would appreciate if someone have an idea.

Thanks for your time in advance.
