Anything in Asterisk can originate an outgoing channel and call a
device. You can use the AMI originate or CLI command as a basis to
understanding that.

What you can't do is pretend a SIP INVITE arrived into Asterisk somehow
and create a SIP channel and send it into the dialplan. You can only
place an outgoing call to a device that once answered goes where you
want.

If this isn't what you need to do then there's nothing really built in
to do what you want precisely.
