;install odbc on asterisk running container 
This installs:
asterisk-odbc → Asterisk's ODBC module
unixodbc → ODBC driver manager
unixodbc-dev → Development files for ODBC
mariadb-client → MySQL/MariaDB client tools (for testing)

sudo docker exec -it mat_asterisk sh -c "apk add --no-cache asterisk-odbc unixodbc unixodbc-dev mariadb-client"



THEN CHECK USING THIS
1️⃣ Check If ODBC Modules Are Available
Run this command inside your Asterisk container:

sh
Copy
Edit
sudo docker exec -it mat_asterisk ls /usr/lib/asterisk/modules | grep odbc
This should list files like:

Copy
Edit
res_odbc.so
res_config_odbc.so
cdr_odbc.so
cel_odbc.so
func_odbc.so
If res_odbc.so and res_config_odbc.so are missing, then ODBC support is not installed in Asterisk.

SEEMS to be THE ONLY AVAILABLE for the alpine linux connector 
sudo docker exec -it mat_asterisk sh -c "apk add --no-cache unixodbc"
