You may want to consider diverting via a SIP provider to your friend's
phone instead of to the Sipgate number. Then you will have no need of a
SIP phone at your friend's.

Yes.

No.

Just forward the call to your SIP-ID on a line registered with Sipgate.

There is nothing on their website indicating any call forwarding is
possible. Except to voicemail. But I am not clear on what you want here.

May I correct your final comment. Sipgate's network is closed not only
to providers of a commercial service but to everyone who is not a
customer.
