> clear.  instead of talking in pseudo code, post a small example of real code

_phonebook_get ()
{
    local NAME="$1"
    local NUMBER

    # returns a valid phonenumber, if entry exists
    # otherwise returns false

    ...
}

_send_sms ()
{
    local DESTINATION="$1"
    local TEXT="$2"
    local PROVIDER="$( uci get system.service.sms.provider )"

    local NUMBER="$( _phonebook_get $DESTINATION )" || {
                         logger "user '$DESTINATION' unknown"
                         return 1
                 }

    _send_sms_$PROVIDER "$NUMBER" "$TEXT"
}

is in this case not correctly implemented. Close the ticket, I
have to open a ticket @bug-bash....
