[Kamailio-Users] Trying to make Purple Module work

Hi mani,

I'm not sure where to start...

* Copying the the overview in the module doc:
*"Purple module is a multi-protocol instant-messaging gateway module which
use libpurple, the library on bottom of Pidgin (ex-gaim). **This plugin was
wrote in order to proof the concept of gateway between SIP and MSN/Live
networks. **[...] **It's no really adapted to a production environment with
a huge user count but can be used in order to demonstrate the concept or to
use it in SOHO environment."*
**
To be clearer, for the moment, just try it and give your feedback, but do
not hope to have a userfriendly and stable IM federation.

Currently there is mainly two way to have IM&Presence "Federation" :
1) use a multi-protocol client, which will handle all your accounts and will
display all your separate buddylist as a single one and will use the
appropriate protocol for each buddy. Pidgin and Trillian working like this,
but it's not a real federation, cause you still have multiple identities
running on your computer.
2) use a single-protocol client with a gateway. The gateway is then
responsible to connect with all your accounts you given. That's how work
purple+kamailio, gtalk-2-msn bridges, skype... This a real federation
because you have only one identity on your computer.

There is also a third way, which is only acceptable for a sip-xmpp gateway
(like XMPP kamailio's module), because sip and xmpp are both open protocols
with server-to-server communication.

About the externals buddylists :
With the first federation solution, it's implied, cause your client will
handle directly each list.
But with the second, you need a way to propagate the external list to the
client, and more important a way to say the gateway that you're trying to
use another protocol. With skype and gtalk bridge, is quite simple cause the
developpers handle both gateway and client, so they can do what they want.
With purple module is more difficult, cause we want to be able to use any
sip client... Finally the solution sounds to be XCAP and centralized
buddylist filled by the module, but you'll still need a way to say the
gateway which protocol to use, only with the R-URI (with the URI filtering I
mentioned I previous mails).

I hope this informations will help you understand better the problems.
I know purple isn't finished yet, it's a first version, and need a lot of
improvements to be user friendly.


Regards,

Eric.
