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})
