If you have only static IPs, then it's easy to write each rules
including the domains and ips. But I guess you don't?

That's a great idea!

The ideal way would be to add a new variable in the filter plugin
configuration:

 dialingplan  internal
 #dialingplan external
 #dialingplan both

This would need a very few change in the filter plugin.

I just tried to modify partysip to make it possible to
load several instance of the same plugin. With the above
fix, this would be enough.

The idea is to use this config:

plugins = udp syntax rgstrar filter filter ls_localdb ls_sfull
plugins_config = udp syntax rgstrar filter_internal filter_external ls_localdb 
ls_sfull

so that you can specify the same plugin several times with different
configuration in partysip.conf for each filter plugin Aymeric

But.... It does not work!
When a new request is received it is processed by both filter plugin
but the configuration used by both instance is the second one!

The global pointer 'filter_context' of both plugins points to the same
memory... I don't know yet the best way to resolv this...
