Currently our setup is a proxy server in front of 3 registrar servers 
and a seperate, single, presence server. On the proxy we forward 
REGISTER to the registrars using dispatcher, and PUBLISH/SUBSCRIBE over 
to the presence server. On the client we have the address of the proxy 
defined for registration and presence.

When you mention SUBSCRIBE is forwarded to registrar above, do you mean 
that we save the subscription aor using the registrar/usrloc module(s) 
before forwarding to presence server? I don't see anything in the 
documentation for subscriptions, or does it even matter what sip method 
hist the registrar/usrloc when saving?

If we are able to save subscriptions in urloc, when the standalone 
presence server sends a notify out, is it then expecting to perform a 
registrar lookup for aor details before relaying?

Thanks
