[sr-dev] Reloading kamailio.cfg on the fly

[Carlos Ruiz Díaz]

Hi Rahul,

currently, there's no way of updating those values on-the-fly. That
information is stored in memory and after a restart everything gets lost,
so you have to make sure no calls are active before doing the restart. This
is only true for cnxcc, and not for dialog module for example, which has
the option of backing everything up to a permanent storage such a database.

Regards,
