Can I blind transfer to a group of extensions?

Im using the SIP protocol and I would like to transfer a call to a group of extensions but with the following conditions.

  1. I would like the extensions not to ring but only show incoming line.
  2. I would like the call to ring but not transfer to the autoattendant if no one answers.

I still would like to have the regular transfer available. Its just that this new way would have its own button on the phone.

Can * do this? Would this require an AGI script?
