asterisk ODBC Data source name not found debian 9

Question

I've been trying to get odbc working with asterisk.

As of now, I think the fault is with ODBC/driver/packages as I am not able to even run isql command and get output:

Error : 
root@odbctest:/home/scsupport# isql -v asterisk-connector asterisk asterisk
[IM002][unixODBC][Driver Manager]Data source name not found, and no default driver specified
[ISQL]ERROR: Could not SQLConnect
root@odbctest:/home/scsupport#

Below is quick rundown

1. Mysql is configure
2. odbc.ini and odbcinst.ini are setup
3. Have installed required packages but still not sure if i have missed any
4. Downlaoded mariaDB wget https://downloads.mariadb.com/Connectors/odbc/connector-odbc-2.0.19/mariadb-connector-odbc-2.0.19-ga-debian-x86_64.tar.gz

I have followed asterisks guide page but of course packges will be different so I have used apt-cache search to find packages

Guide I followed is : https://wiki.asterisk.org/wiki/display/AST/Getting+Asterisk+Connected+to+MySQL+via+ODBC

Here are details system and setup :
