[SR-Users] msilo is failing to in db connection...

[Krishna Kurapati]

Hi,

It finally worked. I reconstructed the config file step by step with the
same modparam() and it worked.
Still not sure what really was wrong before.

The other day, I tried to create routes for sending asynchronous messages
to web service and the entire system
stopped working. The routes became  empty. The config parser never
complained. I rebuilt the config file and checked
to see if the file is ok by running Kamailio step by step. I could not
trust kamailio config check since it is
the one that threw me off track.

Are there any best practices out there in constructing long config file?
Is it possible to create smaller modular config files and link them to
create the system? Or a better tool to
identify errors in the config file?

Best,
Krish Kura
