...although SIP accounts are currently connected (IPPI, IPTEL) - checked
under properties/accounts (Mac OS 10.7.4)
probably a new feature and not a bug (?) as only those connections are
shown were buddies are currently online.
However it is not clear if the other connections are working (SIP
accounts in this case) as not shown in the drop-down menu under my name,
so the user has to check via properties/accounts
