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.

 So, if the client aren't able to perform this function. Can SER do that? Or

  functions. Correct me if I'm wrong.

 Thanks.

 When your client registers to SER as a particular user, that 
 registration is stored in SER.

 If you register multiple times with the same user, ALL of those contacts 
 are called when a call is sent to that user.
