Hi All,
I'd like to ask the guru's out there their opinion on how to solve the
nat problem for presence subscriptions.
We have an issue with subscriptions that get timed out and the notify
clears the subscription out of the active_watchers table due to the
notify timing out, I think this is expected and the right way to do it.
However, how do others out there ensure that their subscription nat
states are kept alive? For registrations we have nathelper, but, what is
the sanest way of doing the same for subscriptions?
I was originally thinking of sending notifications through our
registrar/lookup server, but, I'm not sure if that is the correct way
to do it.
Any thoughts, tips, tricks would be much appreciated.
Cheers

Hello,
you have presence server configured as a different address in client
than the register? Typically the register and subscribe go same path up
to register and from there the subscribe si forwarded to a dedicated
presence server, if it is the case.
Cheers,
Daniel

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.
Typically the register and subscribe go same path up
to register and from there the subscribe si forwarded to a dedicated
presence server, if it is the case.
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

Hello,
Just a thought, have you looked at the nat_traversal module? It's worked
well for us in similar scenarios.
Cheers,
Charles
