Ringing multiple clients is something the server does -- not the client.

Eg:

User A logs into SER with IP:22.33.44.55 and leaves his client 
running.   He then goes to work and logs into SER with IP: 88.99.66.77

In SER, there's now a table that has that information:

User A: 22.33.44.55, 88.99.66.77

When user B calls, SER rings every place User A is logged in from. The 
first phone to answer gets the call.



Call pickup is something completely different. And yes, for that, you'd 
need Asterisk running.
