[asterisk-users] ODBC connection failure - can it be fatal?

I have an Asterisk 13.14.1 setup which uses ODBC to write CEL and CDR records.

The connection to my database server depends on a VPN tunnel being up, and if 
Asterisk starts before that tunnel is functional, I get messages such as the 
following in the Asterisk log file:

[2020-06-23 10:40:22.384335] delta WARNING[1697]: res_odbc.c:958 in 
odbc_obj_connect: res_odbc: Error SQLConnect=-1 errno=1045 [unixODBC]
[ma-3.0.6]Access denied for user 'Trimble'@'delta.example.net' (using 
password: YES)

The problem is that this is not a fatal error as far as Asterisk is concerned, 
so it continues to start up to the point where I get:

[2020-06-23 10:40:26.076377] delta VERBOSE[1697]: asterisk.c:4791 in 
asterisk_daemon: Asterisk Ready.

and the system then processes calls without creating any CEL or CDR entries.

Is there any way I can tell Asterisk that an ODBC connection problem is a 
fatal error, so please shut down and don't process any calls (I have an HA 
setup so another machine will handle any calls which needs processing; I just 
don't want to process calls without generating CDRs)?



"Can you keep a secret?"
"Well, I shouldn't really tell you this, but... no."
