Subject: [asterisk-users] Cut off last character of EXTEN

 

Hello,

how can I cut off the last character of the EXTEN-variable with variating
length ?

So I have :

112233#
123#
123456789#

I want to cut off the last character.

${EXTEN:-1} gives me #, but that is the character I want to cut off.



Kind regards,
Jonas.

 

Here ya go:

 

112233# use ${EXTEN:0:6})

123# use ${EXTEN:0:3})

123456789# use ${EXTEN:0:9})
