[Users] How to setup the openser with presence function? - sr-users

27 May 2007

Hi all,

I use two X-Lite SIP clients with Contact list supported. I want to use chat
(text mode) with each sip clients(X-Lite) via Openser.
I study the documents of Openser ( http://openser.org/docs/ ), I think the
modules ( presence, pua, pua_usrloc, pua_mi ) should what I need.
But I don't know how to set it up. I can't see any online or offline
information for both Xlite1 and Xlite2. Of couse, I add both of them as
friends in contact list on X-Lite software.

Can anyone kind to give me some tips or any URL to reference please?

Xlite1  ==chat==> Openser ==Chat==> Xlite2

# -- presence params --
loadmodule "presence.so"
modparam("presence", "db_url",
"mysql://openser:openserrw@localhost
/openser")
modparam("presence", "max_expires", 3600)
modparam("presence", "force_active", 1)
modparam("presence", "server_address", "sip:127.0.0.1:5060"
)

#### I don't know how to configure them in DB
