[asterisk-dev] Re: [asterisk-users] convert URI string to lowercase

[Pavel Jezek]

thank you for tip, seems that app_backticks will do exactly what I want, 
but as asterisk addon, is it compatible with asterisk 1.4?
maybe this is also idea for developers to add something like this app to 
main asterisk tree, because current asterisk lack function/application 
for converting strings to lower od upper cases
I think it would be usefull when working with URI (incoming URI strings 
should be "normalized" to further processing in dialplan, eg. lookup in 
DB or ldap)
