So far, I've been trying out the following which seems to work OK for online
subscribers, but not as well when a "group" call member is a DAHDI phone
routed from/to Asterisk. Just didn't know if someone had better/different
ideas.

That's a good idea for me since the majority of subscribers are using TLS with
CSipSimple which is supposed to have support for +sip.instance.
branch_route[MANAGE_BRANCH] {
...
if(@contact.uri.user==@ruri.user &&
@contact.uri.hostport==@ruri.hostport) {
drop();
}
...
}
