No, not with Betamax-providers (like VoipDiscount). Only one client is
allowed at the same time. Clients (softclient or ATA) periodically
"register" theirselves. The one who sent the last REGISTER is the one that
will be logged in (and will get any incoming calls).

When using the VoipDiscount softclient, you even will get a notification
that another client is logged in, and it will ask you if you want to
re-login, before re-registering.
