[asterisk-users] Asterisk 1.4 + Presence

[Alejandro Cabrera Obed]

Dear all, I'm using Asterisk 1.4 as my SIP server of my LAN users. The
SIP clients are using different operating systems such Debian, Gentoo
and Windows XP so they use different SIP softphones like SJPhone,
Twinkle and X-Lite.

In order to let SIP clients to see the presence status to each other, do
I have to establish any special setting in Asterisk 1.4 ??? Or the
presence status (online, offline, away, etc.) is only up to the SIP
clients and not up to the Asterisk ???

Really thanks

Alejandro
