I have gone a bit further and installed Asterisk 13 LTS from source in
Debian 9 64 bit. It works fine with ODBC and asterisk listens on port 5080.
I have installed Kamailio 5.2 from repository (deb.kamailio) and it started
OK for the default config.
When i try to insert in the Kamailio config, the Asterisk handle, it fails
to start. Could someone give me a hand over here to see the code attached
please(my kamailio.cfg)?

here is the error:
