The active call is affected by operations such as transfer or call parking.
One exception is the New Call action, which uses the primary account by
default; this can be overridden by pressing another line key to initiate the
call.
Joining calls into a specific conference always uses the conference server
of the primary account. Accounts which cannot access the server cannot
join the server.
After you create a ad-hoc conference, you can join additional calls into the
same conference. You cannot create more than one ad-hoc conference
at a time.
Three-way calls can join any two calls, regardless of the account. The
service package of the account to which a call is associated determines
which operations (for example, Call Park) are available on that call. After
you have established a 3-way call, the join functionality becomes
unavailable until the 3-way call is terminated.
Figure 49 on page 294 shows two examples of the IP Deskphone with
one call and multiple calls.

Only the primary account can send or receive instant messages.
Incoming messages for secondary accounts are rejected; they are not
displayed on screen, and are not added to the instant message logs.
