[SR-Users] kamailio asterisk

Hello Everyone, 
I wonder in my case why kamailio is not bridging between TLS and UDP ? Is there additional configuration required ? 

Slava.

You don't need to run kamailio through gdb. If it crashes, then you get 
a corefile -- in the logs it says the name of the file. It is usually 
located in / or in the path you gave to -w parameter. 

After you reproduced the crash, locate the corefile and run gdb like: 

gdb /path/to/kamailio /path/to/corefile 
bt full 

The /path/to/kamailio should be /usr/sbin/kamailio if you installed from 
rpms. 

If you have improvements to init or sysconfig kamailio file, send a 
patch and we will include the changes in kamailio repository. 

Cheers, 
Daniel
